Washington, wary of the dangers posed by an individual's becoming entrenched in the presidency, created a two-term tradition that remained intact until Franklin Delano Roosevelt's third consecutive election in 1940.
Theodore Roosevelt, Franklin's distant cousin, might be said to have violated the tradition in 1912, when he ran for what would (sort of) have been a third term, but his is a strange case. Roosevelt was elected as Vice President in 1900, and became president in September of 1901, 6 months into the second term of President William McKinley when McKinley died in office.
