A highly centralized public school system was installed in 1901, using English as the medium of instruction. This created a heavy shortage of teachers, and the Philippine Commission authorized the Secretary of Public Instruction to bring to the Philippines 600 teachers from the U.S.A. — the so-called Thomasites. Free primary instruction that trained the people for the duties of citizenship and avocation was enforced by the Taft Commission per instructions of President McKinley. Also, the Catholic Church was disestablished, and a considerable amount of church land was purchased and redistributed.
