Roosevelt was a leader of the progressive movement, and he championed his 'Square Deal' domestic policies, promising the average citizen fairness, breaking of trusts, regulation of railroads, and pure food and drugs. He made conservation a top priority and established many new national parks, forests, and monuments intended to preserve the nation's natural resources. In foreign policy, he focused on Central America where he began construction of the Panama Canal. He was the second of four children born to socialite Martha Stewart 'Mittie' Bulloch and businessman and philanthropist Theodore Roosevelt Sr. (brother of Robert Roosevelt and James A. Roosevelt, all sons of Cornelius Roosevelt). He had an older sister, Anna (nicknamed 'Bamie'), a younger brother, Elliott, and a younger sister, Corinne.
