The last time Congress created a new state
On March 12, 1959, Congress approved Hawaii for admission to the union as the 50th state, marking the last time statehood was subject to votes in the House and Senate.
President Dwight Eisenhower signed the Hawaii Admissions Act a week later on March 18, 1959, and Hawaii officially became the 50th state on August 21, 1959, after Hawaiians voted to become a state in June 1959 under terms specified in the Admissions Act.
