In 1911, Bolton became a professor at the University of California, Berkeley. There he served as the chair of the history department for twenty-two years and became the founding director of the renowned Bancroft Library. In his book The Americas, George P. Hammond noted, “the next twenty years might well be called the Bolton era in historical studies at the University of California.” In his dual capacity as founding director and chairperson, he made Bancroft Library a great research center for American history and elevated his department into a top-ranking position in the historical world. Bolton was involved with the 1918 founding of The Hispanic American Historical Review, the first specialized journal of Latin American history, serving as an advisory editor. He taught the "History of the Americas" course, which enrolled up to a thousand students. His round-table seminar became famous, and the historians trained in that group have long been known as the “Bolton School.” At Berkeley he supervised more than 300 Masters theses and 104 doctoral dissertations, an all-time record. In 1914, Bolton published Athanase de Mézières and the Louisiana-Texas Frontier, 1768–1780. A year later, Bolton published Texas in the Middle Eighteenth Century: Studies in Spanish Colonial History and Administration. He declined the presidency of the University of Texas. Over the next twenty-nine years, Bolton published many works, including Texas in the Middle Eighteenth Century (1921), The Spanish Borderlands (1921), Outpost of Empire (1931), Rim of Christendom (1936) and Coronado (1949), for which he received a Bancroft Prize from Columbia University.
