In a parliamentary system, by contrast, the legislature holds supreme power. The prime minister is chosen by members of the legislature (Parliament) from among their own number and in practice is the leader of the majority party in the legislature.
There are 435 Representatives in the House of Representatives. The number of members in the House of Representatives is a different story and is based on population.
There are 435 members of the House of Representatives. Federal law determines how many members are in the House of Representatives. The law was passed on Aug. 8, 1911. That measure raised the number of representatives to 435 from 391 because of population growth in the United States. The first House of Representatives in 1789 had only 65 members. The number of seats in the House was expanded to 105 members after the 1790 Census, and then to 142 members after the 1800 head count. The law that set the current number of seats at 435 took effect in 1913.
