DossierThe Stewardship Theory
Theodore Roosevelt believed the president could do anything the Constitution did not explicitly forbid if it served the national interest. That stewardship theory marked a clear break from narrower conceptions of executive passivity.
He used that theory to justify a more energetic federal role in labor conflict, antitrust enforcement, conservation, and foreign-policy projection. This is one of the key moments when the presidency starts to look recognizably modern.
Domestic Reform And Imperial Reach
At home, Roosevelt used the office to mediate industrial conflict and to publicize reform. Abroad, he linked executive prestige to strategic ambition, especially in the Caribbean and Pacific worlds.
He matters because he fused public performance, reform politics, and power projection into one model of leadership. Later activist presidents repeatedly operated inside the space he helped create.
