“President, Wilson changed the nation’s economic policies and led the United States into World War I in 1917. He was the leading architect of the League of Nations, and his progressive stance on foreign policy came to be known as Wilsonianism.”

President Woodrow Wilson
Inside History: “When war broke out in Europe in 1914, the United States vowed to remain neutral. The American people had no interest in becoming entangled in European alliances and empires. President Woodrow Wilson, a progressive Democrat, won reelection in 1916 on the slogan “He kept us out of war.”
“Vowing to defend American lives and make the world “safe for Democracy,” Wilson and the U.S. Congress declared war on Germany in April of 1917.”
“Wilson was very conscious that America didn’t want to get in the war,” says John Thompson, author of Woodrow Wilson: Profiles in Power. “The only way he could resolve that dilemma was to do everything he could to bring the European war to an end.”
“Wilson and his advisors recruited a team of 150 political and social scientists to research the root causes of the war in Europe. That group, known as “The Inquiry,” produced nearly 2,000 reports and 1,200 maps that were boiled down to 14 key recommendations to achieve a stable peace in Europe.”
