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.

Although the Second Republic was inaugurated in December 1972, the National Assembly did not approve the new constitution until August 1973. The document was modelled on the Soviet Union's one-party system. The constitution asserted the supremacy of the single party (UNIP), but did not include the Commission's more liberal recommendations, such as placing limits on detention without trial, restricting the President to serve only two five-year terms, and sharing the President's executive powers with a Prime Minister. The liberal recommendations would also have required electoral competition for the post of President, and prevented him from vetoing parliamentary candidates. Although many of the report's recommendations were ignored, it had a lasting influence: it was cited during the debate on the return to multi-party democracy in 1990–91, and again during the campaign to stop President Frederick Chiluba running for a third term in 2001.
