<u>82</u> years passed between the Monroe doctrine and its exten-sion the Roosevelt coro-llary.
In his annual mess-ages to Congress in 1904 and 1905, Presi-dent Theodore Roosevelt expan-ded the Monroe Doctrine. The corollary sta-ted that not only were the nati-ons of the Western Hemisphere not open to coloni-zation by European powers, but that the Uni-ted States had the respons-ibility to preserve order and pro-tect life and pro-perty in those countries.
In the history of United States foreign poli-cy, the Roosevelt Corollary was an add-ition to the Monroe Doctrine articul-ated by President Theodore Roosevelt in his State of the Uni-on address in 1904 after the Vene-zuelan crisis of 1902–1903.
