In 1862, in the only instance of a Jewish expulsion in America, General Ulysses S. Grant banished Jewish citizens from the region under his military command. Although the order was quickly revoked by President Lincoln, it represented growing anti-Semitism in America. Convinced that assimilation was their best defence, Jews sought to Americanise by shedding distinctive dress, occupations, and religious rituals. American Jews recognised the benefit and urgency of bridging the divide between Reform and Orthodox Judaism to create a stronger alliance to face the challenges ahead. With Grant's 1868 presidential campaign, they also realised they could no longer remain aloof from partisan politics. As they became a growing influence in American politics, both political parties courted the new Jewish vote. Once in office, Grant took notice of the persecution of Jews in Romania and Russia, and he appointed more Jews to office than any president before him. Indeed, Simon Wolf, a Washington lawyer who became one of Grant's closest advisers, was part of a new generation of Jewish leaders to emerge in the post-Civil War era--thoroughly Americanised, politically mature, and committed to the modernised Judaism of the Reform movement.
