, making it the youngest of the major world religions.

He continued to preach until his death in 632.

Muslims are monotheistic and worship one, all-knowing God, who in Arabic is known as Allah.

Followers of Islam aim to live a life of complete submission to Allah

Mosques are places where Muslims worship.

The prophet Muhammad

was born in Mecca, Saudi Arabia, in 570 A.D

Muslims believe he was the final prophet sent by God to reveal their faith to mankind.

Starting in about 613, Muhammad began preaching throughout Mecca the messages he received. He taught that there was no other God but Allah and that Muslims should devote their lives to this God.

n 622, Muhammad traveled from Mecca to Medina with his supporters. This journey became known as the Hijra

marks the beginning of the Islamic calendar.

The word “Islam” means “submission to the will of God.”

After Muhammad’s passing, Islam began to spread rapidly.  A series of leaders, known as caliphs, became successors to Muhammad. This system of leadership, which was run by a Muslim ruler, became known as a caliphate.

During the reign of the first four caliphs, Arab Muslims conquered large regions in the Middle East, including Syria, Palestine, Iran and Iraq. Islam also spread throughout areas in Europe, Africa, and Asia.

he caliphate system lasted for centuries and eventually evolved into the Ottoman Empire, which controlled large regions in the Middle East from about 1517 until 1917, when World War I ended the Ottoman reign.

When Muhammad died, there was debate over who should replace him as leader. This led to a schism in Islam, and two major sects emerged: the Sunnis and the Shiites.

The Quran (sometimes spelled Qur’an or Koran) is considered the most important holy book among Muslims.

t contains some basic information that is found in the Hebrew Bible as well as revelations that were given to Muhammad.

The book is written with Allah as the first person, speaking through Gabriel to Muhammad. It contains 114 chapters, which are called surahs.

The Islamic calendar, also called the Hijra calendar, is a lunar calendar used in Islamic religious worship. The calendar began in the year 622 A.D., celebrating the journey of Muhammad from Mecca to Medina.

Muslims follow five basic pillars that are essential to their faith. These include:Shahada: to declare one’s faith in God and belief in MuhammadSalat: to pray five times a day (at dawn, noon, afternoon, sunset, and evening)Zakat: to give to those in needSawm: to fast during RamadanHajj: to make a pilgrimage to Mecca at least once during a person’s lifetime if the person is able

Islam’s legal system is known as Sharia Law. This faith-based code of conduct directs Muslims on how they should live in nearly every aspect of their lives.

The prophet Muhammad is credited with building the first mosque in the courtyard of his house in Medina.

Muslim prayer is often conducted in a mosque's large open space or outdoor courtyard. A mihrab is a decorative feature or niche in the mosque that indicates the direction to Mecca, and therefore the direction to face during prayer.

Men and women pray separately, and Muslims may visit a mosque five times a day for each of the prayer sessions.

The long and triumphant reign of its first emperor, Augustus, began a golden age of peace and prosperity;

As legend has it, Rome was founded in 753 B.C. by Romulus and Remus,

twin sons

Romulus became the first king of Rome,

Rome’s era as a monarchy ended in 509 B.C.

The power of the monarch passed to two annually elected magistrates called consuls. They also served as commanders in chief of the army.

Politics in the early republic was marked by the long struggle between patricians and plebeians (the common people), who eventually attained some political power through years of concessions from patricians

In 450 B.C., the first Roman law code was inscribed on 12 bronze tablets–known as the Twelve Tables–and publicly displayed in the Roman Forum.

By around 300 B.C., real political power in Rome was centered in the Senate, which at the time included only members of patrician and wealthy plebeian families.

During the early republic, the Roman state grew exponentially in both size and power

Rome then fought a series of wars known as the Punic Wars with Carthage, a powerful city-state in northern Africa. The first two Punic Wars ended with Rome in full control of Sicily, the western Mediterranean and much of Spain. In the Third Punic War (149–146 B.C.), the Romans captured and destroyed the city of Carthage and sold its surviving inhabitants into slavery, making a section of northern Africa a Roman province.

Rome’s military conquests led directly to its cultural growth as a society, as the Romans benefited greatly from contact with such advanced cultures as the Greeks.

The first Roman literature appeared around 240 B.C., with translations of Greek classics into Latin; Romans would eventually adopt much of Greek art, philosophy and religion.

Rome’s complex political institutions began to crumble under the weight of the growing empire, ushering in an era of internal turmoil and violence.

The gap between rich and poor widened as wealthy landowners drove small farmers from public land,

When the victorious Pompey returned to Rome, he formed an uneasy alliance known as the First Triumvirate

After earning military glory in Spain, Caesar returned to Rome to vie for the consulship in 59 B.C.

Caesar received the governorship of three wealthy provinces in Gaul beginning in 58 B.C.

In 49 B.C., Caesar and one of his legions crossed the Rubicon, a river on the border between Italy from Cisalpine Gaul

Consul Mark Antony and Caesar’s great-nephew and adopted heir, Octavian, joined forces to crush Brutus and Cassius and divided power in Rome with ex-consul Lepidus in what was known as the Second Triumvirate. With Octavian leading the western provinces, Antony the east, and Lepidus Africa, tensions developed by 36 B.C. and the triumvirate soon dissolved. In 31 B.C., Octavian triumped over the forces of Antony and Queen Cleopatra of Egypt (also rumored to be the onetime lover of Julius Caesar) in the Battle of Actium

To avoid meeting Caesar’s fate, he made sure to make his position as absolute ruler acceptable to the public by apparently restoring the political institutions of the Roman republic while in reality retaining all real power for himself. In 27 B.C., Octavian assumed the title of Augustus, becoming the first emperor of Rome.

By 29 B.C., Octavian was the sole leader of Rome and all its provinces.

Augustus’ rule restored morale in Rome after a century of discord and corruption and ushered in the famous pax Romana–two full centuries of peace and prosperity.

He instituted various social reforms, won numerous military victories and allowed Roman literature, art, architecture and religion to flourish.

When he died, the Senate elevated Augustus to the status of a god, beginning a long-running tradition of deification for popular emperors.

The decadence and incompetence of Commodus (180-192) brought the golden age of the Roman emperors to a disappointing end. His death at the hands of his own ministers sparked another period of civil war, from which Lucius Septimius Severus (193-211) emerged victorious.

Meanwhile, threats from outside plagued the empire and depleted its riches, including continuing aggression from Germans and Parthians and raids by the Goths over the Aegean Sea.

Diocletian divided power into the so-called tetrarchy (rule of four), sharing his title of Augustus (emperor) with Maximian. A pair of generals, Galerius and Constantius, were appointed as the assistants and chosen successors of Diocletian and Maximian; Diocletian and Galerius ruled the eastern Roman Empire, while Maximian and Constantius took power in the west.

The stability of this system suffered greatly after Diocletian and Maximian retired from office. Constantine (the son of Constantius) emerged from the ensuing power struggles as sole emperor of a reunified Rome in 324. He moved the Roman capital to the Greek city of Byzantium, which he renamed Constantinople. At the Council of Nicaea in 325, Constantine made Christianity (once an obscure Jewish sect) Rome’s official religion.

An entirely different story played out in the west, where the empire was wracked by internal conflict as well as threats from abroad–particularly from the Germanic tribes now established within the empire’s frontiers like the Vandals (their sack of Rome originated the phrase “vandalism”)–and was steadily losing money due to constant warfare.

Rome eventually collapsed under the weight of its own bloated empire, losing its provinces one by one:

In September 476, a Germanic prince named Odovacar won control of the Roman army in Italy.

After deposing the last western emperor, Romulus Augustus, Odovacar’s troops proclaimed him king of Italy, bringing an ignoble end to the long, tumultuous history of ancient Rome. The fall of the Roman Empire was complete.

Roman aqueducts, first developed in 312 B.C., enabled the rise of cities by transporting water to urban areas, improving public health and sanitation.

Roman cement and concrete are part of the reason ancient buildings like the Colosseum and Roman Forum are still standing strong today.

Roman arches, or segmented arches, improved upon earlier arches to build strong bridges and buildings, evenly distributing weight throughout the structure.

Roman roads, the most advanced roads in the ancient world, enabled the Roman Empire

Although many students learn about the historical struggles to desegregate schools in the civil rights era, segregation as a current reality is largely absent from the curriculum.

integration is still one of the most effective tools that we have for achieving racial equity.”

Based on civil rights data released by the United States Department of Education, the nonprofit news organization ProPublica has built an interactive database to examine racial disparities in educational opportunities and school discipline. In this activity, which might begin a deeper study of school segregation, you can look up your own school district, or individual public or charter school, to see how it compares with its counterparts.

Only a tiny number of black students were offered admission to the highly selective public high schools in New York City in 2019, raising the pressure on officials to confront the decades-old challenge of integrating New York’s elite public schools.

School districts that predominantly serve students of color received $23 billion less in funding than mostly white school districts in the United States in 2016, despite serving the same number of students, a new report found.

Segregation still persists in public schools more than 60 years after the Brown v. Board of Education decision.

On average, seasonal flu strains kill about 0.1 percent of the people they infect.

The coronavirus, on the other hand, has killed more than 210,000 people in the United States, and more than one million worldwide, since the start of 2020.

Still, estimates from experts tend to put the coronavirus’s death rate higher than the flu’s.

Researchers still don’t fully understand the long-term consequences of coronavirus infections, which have saddled a growing number of people, called long-haulers, with serious and debilitating symptoms that can linger for weeks or months.

Medical experts have also warned that as the northern hemisphere cools for winter, the flu and Covid-19 could collide, fueling a new spate of deaths.
