Across much of the globe, the history of Roman Catholicism from the 15th Century through the 18th Century was largely synonymous with Spanish Colonialism. Spanish conquests and colonization of nations ranging from Asia to the Americas had increased Christian converts by the millions. These conversions later led to the full conversion of countries to Christianity. However, during the 19th and early 20th Centuries, many liberal governments started to promote anti-clerical laws which would cut down the authority of the Catholic Church withing their countries' borders. These laws soon led to the annihilation of many religious leaders' power, and the destruction of the Church's presence in governance.

The Explosion of Catholicism

Christian Catholicism was one of the means that the Spanish government used to colonize the New World. The real objective was to extend Spanish sovereignty over these nations. Although conversion to Christianity was a byproduct of Spanish rule and slavery, it was actually the Catholic Church in the Americas that raised its voice against slavery and cruelty to natives. Then, the 19th Century started the Vatican control of these colonies, and even allowed for the ordination of native clergy. These developments gave way to full Catholicism of Spain's former colonies, an effect that still lives on today.

Historical, Cultural, and Geopolitical Significance of Catholicism

The legacies left by the Spanish Conquistadors are still evident today, and can be seen in the majority of Catholic Christian populations in Asia, Europe, and the Americas. Historically, Catholic priests improved the lives of the indigenous peoples. The Clergy in converting the natives disallowed freedom of religion which today still persists in most areas. The separation of state and church began in the early 19th Century and spread to almost all former Spanish possessions. These provocations of the church led to many excommunications. Political repercussions and religious persecutions became the norm in the mid-20th Century when governments tried to stop the clergy from siding with the poor. As a result, "Liberation Theology" was introduced, and the movement gained ground. Conversely, today "Christian Revival" movements hope to supplant the former.
