If efforts at social integration had succeeded despite such attitudes, British India might have developed into a casta-ranked society like the Spanish Americas. But the need to win the support of the indigenous clerical classes, as well as the fear of promoting a Creole elite like the treacherous Americans, led the East India Company onto a different track. In the last few decades of its rule, before the revolt of 1857, Eurasian clerks were gradually displaced in state service by Indians from the traditional clerical classes, both Hindu and Muslim and, around Bombay, also Parsi and Goan Catholic. A greater regard by the British for their own “blood” returned after 1857, when Anglo-Indians were extensively recruited into the developing railway system in order to ensure imperial control of this strategic asset. Eurasians, however, could not compete with the indigenous clerical classes in subordinate employment, that is to say, clerical work.
