William Howard Taft was the 27th U.S. president (1909-1913), a Progressive Era Republican who continued trust-busting at home, promoted Dollar Diplomacy abroad, and whose break with Theodore Roosevelt split the Republican Party in the election of 1912.
William Howard Taft was Theodore Roosevelt's hand-picked successor, elected in 1908 with the expectation that he'd carry the Progressive torch. In some ways he did. His administration actually filed more antitrust suits than Roosevelt's, and the 16th Amendment (income tax) and 17th Amendment (direct election of senators) both moved forward during his term. But Taft kept disappointing progressives. He signed the Payne-Aldrich Tariff, which barely lowered rates, and he fired conservationist Gifford Pinchot in the Ballinger-Pinchot controversy, which made him look like he'd abandoned Roosevelt's conservation legacy.
In foreign policy, Taft is the face of Dollar Diplomacy, the idea that the U.S. should use investment and loans (instead of just military force) to expand American influence in Latin America and East Asia. That makes him a useful example of the imperialist attitudes in Topic 7.2, where economic opportunity was a core argument for expansion. The Roosevelt-Taft feud exploded in 1912, when Roosevelt ran against him on the Bull Moose (Progressive Party) ticket, split the Republican vote, and handed the White House to Woodrow Wilson. After his presidency, Taft became the 10th Chief Justice of the United States, the only person to hold both jobs.
Taft sits at the intersection of two major Unit 7 threads. For Topic 7.4 (LO APUSH 7.4.A), he's evidence that Progressives were divided. The same president could break up trusts and still get labeled a sellout by reformers. The Ballinger-Pinchot affair also plugs directly into LO APUSH 7.4.B on attitudes toward natural resources, since it dramatized the fight over how seriously the government should police resource use. For Topic 7.2 (LO APUSH 7.2.A), Dollar Diplomacy is one of the three classic foreign policy approaches you compare on the exam, alongside Roosevelt's Big Stick and Wilson's Moral Diplomacy. If a question asks you to explain different attitudes about America's role in the world between 1890 and 1917, Taft is your economic-influence data point.

Dollar Diplomacy (Unit 7)
This is Taft's signature foreign policy. Instead of sending warships first, Taft wanted American banks and businesses to invest in Latin America and China, betting that economic ties would secure U.S. influence. It's the same imperialist logic from Topic 7.2 (expansion driven by economic opportunity) just wearing a business suit.
Bull Moose Party (Unit 7)
Taft's rightward drift is the reason this party exists. When Roosevelt decided Taft had betrayed progressivism, he bolted the Republicans and ran on the Progressive (Bull Moose) ticket in 1912. The split vote let Wilson win, which is a classic exam example of how third parties shape elections without winning them.
17th Amendment (Unit 7)
Ratified in 1913 at the very end of Taft's term, the 17th Amendment made senators directly elected by voters. It shows that progressive structural reforms kept advancing under Taft even while reformers complained about him, proof that 'Progressive Era president' and 'beloved by Progressives' aren't the same thing.
Progressive Era (Unit 7)
Taft is your go-to example for the CED point that Progressives were divided over many issues. He satisfied the trust-busting wing while alienating the conservation and tariff-reform wings, which makes him perfect evidence for a comparison or 'extent of change' essay about Progressive goals.
Taft usually shows up in two ways. First, multiple-choice and short-answer questions on Progressive Era politics ask you to compare Roosevelt, Taft, and Wilson, often through a 1912 election cartoon or platform excerpt. Second, foreign policy questions ask you to match presidents to approaches, so know that Taft equals Dollar Diplomacy. No released FRQ requires Taft by name, but he's strong evidence for essays under LO APUSH 7.2.A (attitudes about America's role in the world) and LO APUSH 7.4.A (comparing Progressive goals and effects). The move that earns points is specificity. Don't just say 'Taft was less progressive.' Say he signed the Payne-Aldrich Tariff and fired Pinchot, but also filed more antitrust suits than Roosevelt.
Both were Republican Progressive Era presidents who busted trusts, which is why they blur together. The differences are what get tested. Roosevelt used the Big Stick (military muscle, like the Panama Canal) while Taft used Dollar Diplomacy (loans and investment). Roosevelt championed conservation; Taft fired Pinchot and looked weak on it. Roosevelt distinguished 'good' trusts from 'bad' trusts, while Taft's Justice Department sued more broadly. By 1912 they were running against each other, so on the exam, treat them as a comparison pair, not a matched set.
Taft was the 27th president (1909-1913), chosen by Theodore Roosevelt as his successor, and later became the only president to also serve as Chief Justice of the United States.
His foreign policy, Dollar Diplomacy, used American loans and investment to expand U.S. influence in Latin America and East Asia, fitting the economic arguments imperialists made in Topic 7.2.
Taft actually pursued more antitrust suits than Roosevelt, but the Payne-Aldrich Tariff and the Ballinger-Pinchot controversy convinced many Progressives he had abandoned reform.
The Ballinger-Pinchot affair, in which Taft fired conservationist Gifford Pinchot, connects him to the conservation debates covered by LO APUSH 7.4.B.
Roosevelt's challenge to Taft in 1912 split the Republican vote between Taft and the Bull Moose Party, allowing Democrat Woodrow Wilson to win the presidency.
On the exam, Taft works best as the middle term in a Roosevelt-Taft-Wilson comparison of Progressive politics and foreign policy styles.
Taft (1909-1913) continued Progressive trust-busting with more antitrust suits than Roosevelt, promoted Dollar Diplomacy abroad, and signed the Payne-Aldrich Tariff. The 16th and 17th Amendments advanced during his term, and his split with Roosevelt led to the three-way election of 1912.
Partly, and that ambiguity is the point. He out-busted Roosevelt on trusts, but his weak tariff reform and the firing of Gifford Pinchot alienated the Progressive wing. The CED stresses that Progressives were divided, and Taft is a walking example of that division.
Roosevelt's Big Stick relied on the threat of military force, like backing Panama's revolt to build the canal. Taft's Dollar Diplomacy substituted economic power, encouraging American banks to invest in Latin America and China so financial influence would do the work of warships.
Roosevelt believed Taft had betrayed the Progressive agenda, especially after the Ballinger-Pinchot conservation controversy. Roosevelt ran on the Progressive (Bull Moose) ticket in 1912, splitting Republican votes with Taft and giving Woodrow Wilson the presidency.
Yes. After losing in 1912, Taft became the 10th Chief Justice of the United States in 1921, making him the only person in American history to lead both the executive and judicial branches.
