Weber argued that the Protestant religion, initially formed as a spiritual institution, became the ethic that underlay the transition into capitalism. The initial pro-capitalist political parties that formed in Europe reflected the desire to prove success in spiritual life via the accumulation of capital, which became the pinnacle of "worldly calling". As he argued of rationality in general, parties become the formally sanctioned, bureaucratic extension of emotional authority as society transitions into modernity. Parties form primarily in democratic societies because of the ideological differences that can arise between individuals in the same geographic region. Issues with party power As more contemporary theorists have noted, parties tend to become overburdened with demands as they grow larger and lose focus on initial key issues. One example, pursued by Doug McAdam in his writing Political Process and the Development of Black Insurgency, was the Civil Rights Movement. Although the movement initially succeeded and made enormous social and political impact due to its rational and centered goals, the movement began to weaken throughout the 1970s due in part to irreconcilable views touted by its various leaders and sects.
