# 66th United States Congress

The 66th United States Congress was a meeting of the legislative branch of the United States federal government, comprising the United States Senate and the United States House of Representatives. It met in Washington, D.C., from March 4, 1919, to March 4, 1921, during the last two years of Woodrow Wilson's presidency. The apportionment of seats in the House of Representatives was based on the 1910 United States census.
The Republicans won majorities in both the House and the Senate, thus taking control of both chambers.
This is the last congress to have no female members of congress in the House of Representatives, and thus the last time there was an all-male congress (several subsequent congresses, up to the 96th Congress, would have periods with no women in the Senate but several in the House).
