The 116th Congress was sworn in on Thursday, and its diverse new members broke historic barriers on representation.

The new Congress boasts the largest number of female members ever, with more than 100 women serving in the U.S. House alone.

The countrys legislators are likewise at their most racially diverse, with the Congressional Black Caucus and the Hispanic Caucus each welcoming more members than ever before. There are also more Asian-Americans and Pacific Islanders in Congress than ever before.

Thursdays swearing-in also ushered a number of individual historic firsts into power.

Reps. Ilhan Omar (D-Minn.) and Rashida Tlaib (D-Mich.) became the first Muslim women in Congress. Tlaib, who is also the first Palestinian-American woman in the national legislature, wore a thobe a traditional Palestinian dress at the swearing-in for all House members and planned to use the Quran for a later, individual swearing-in ceremony. Omar, who is also the first Somali-American elected to Congress, wore a hijab a first on the House floor, which previously banned lawmakers from donning headwear.
