Background and detail
Background. The 30th Congress was a meeting of the federal legislative branch, comprising the Senate and House of Representatives. It met in Washington, D.C., from March 4, 1847, to March 4, 1849, during the last two years of President James K. Polk's administration. The apportionment of House seats was based on the 1840 United States census.
Elections. Members of the 30th Congress were elected in the 1846 United States elections, including the 1846–47 House of Representatives elections. These elections determined the composition of the legislative branch that convened in 1847. The Congress served until the next elections in 1848, which led to the subsequent Congress.
Capitol. The United States Capitol is the seat of the United States Congress. The decision to locate the capital along the Potomac River was brokered by Alexander Hamilton in exchange for federal assumption of war debt. The Capitol, named by Thomas Jefferson, served as the legislative meeting place for the 30th Congress in Washington, D.C.
