In the 1890s and 1900s, Reed and his successor, Joseph Gurney Cannon (R-Illinois) used the Rules Committee to centralize the power of the Speakership. Although their power to place members in committees and perform other functions was limited by a forced rule change in 1910, the Rules Committee retained its power. However, it ceased to function as the personal project of the Speaker, as it had originally; instead, as the seniority system took root, it was captured by a coalition of conservative Democrats and Republicans. This state of affairs would continue until the 1960s.
