Tiglath-pileser was eager to expand Assyria's access to the Mediterranean Sea,
particularly because he wanted his empire to increase its number of trading
partners and expand its trade routes. His goal brought him into a long conflict
with a variety of nomadic and seminomadic Aramaean tribes, however. For more
than 14 years in the middle period of his reign, Tiglath-pileser launched a
total of 28 campaigns against the Aramaeans, who blocked his unmolested access to the Mediterranean.
He was eventually successful, and the Aramaeans no longer posed a threat to
Assyrian trade.
