The New Deal was first put into place in early 1933, right after Franklin D. Roosevelt became president, with the main wave of initial New Deal laws passed during his “Hundred Days” from March 9 to June 16, 1933.

Key date in one line

  • Franklin D. Roosevelt took office on March 4, 1933, and within days began launching the New Deal, starting with emergency banking legislation on March 9, 1933.

What “put into place” really means

  • The New Deal was not a single law on a single day; it was a series of programs and reforms rolled out between 1933 and 1939.
  • Historians usually treat spring 1933—especially the March–June “Hundred Days” session of Congress—as the moment the New Deal truly went into effect in practice.
