Roosevelt assumed the presidency at age 42, and remains the youngest person to become president of the United States. As a leader of the progressive movement he championed his "Square Deal" domestic policies. It called for fairness for all citizens, breaking of bad trusts, regulation of railroads, and pure food and drugs. Roosevelt prioritized conservation and established national parks, forests, and monuments to preserve the nation's natural resources. In foreign policy, he focused on Central America, where he began construction of the Panama Canal. Roosevelt expanded the Navy and sent the Great White Fleet on a world tour to project American naval power. His successful efforts to broker the end of the Russo-Japanese War won him the 1906 Nobel Peace Prize, making him the first American to ever win a Nobel Prize. Roosevelt was elected to a full term in 1904 and promoted policies more to the left, despite growing opposition from Republican leaders. During his presidency, he groomed his close ally William Howard Taft to succeed him in the 1908 presidential election.
