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.
Czechoslovak Constitution of 1920
The president was elected by both chambers of parliament in joint session (acting in accordance with the standing orders of the lower chamber). The presidential term was seven years, with a two-term limit (the first president was exempted from this provision). Candidates for the presidency had to be at least 35 years old. The framers intended for the prime minister and cabinet to hold the real power. Hence, the constitutional powers of the president were limited. However, the personal prestige of the first two presidents, Tomáš Masaryk and Edvard Beneš, and the instability of successive governments (for example, Masaryk's presidency saw 10 cabinets headed by nine statesmen) meant that the president wielded in practice more authority than the plain text of the constitution suggested. The constitution laid down that all executive functions rested with the government except as expressly assigned to the president. However, the president could address written or verbal messages to parliament, appoint and dismiss ministers, attend and preside over cabinet meetings, and demand written reports from individual ministers. Hence, presidential influence on the executive was in practice considerable.
