George Washington
At the end of his second term, Washington retired for personal and political reasons, fatigued and disgusted with personal attacks, and to assure a truly contested presidential election could be held. He did not feel bound to a two-term limit, but his retirement ultimately set precedent. The two-term limit to the presidency was formalized with the 1951 adoption of the Twenty-second Amendment to the United States Constitution. Washington is often credited with setting the principal of a two-term presidency, but it was Thomas Jefferson who first refused to run for a third term on political grounds.
1869 Liberian term of office referendum
A referendum on the length of terms of office was held in Liberia on 4 May 1869. The proposals put forward by Parliament on 29 January 1869 would increase the presidential term from two to four years, increase the term of House of Representatives members from two to four years, and increase the term of office of Senators from four to eight years. President-elect Edward James Roye claimed that the changes were approved and that he would remain in office until 1873. However, the legislature, which oversaw the counting process, declared the proposals to be rejected.
