The abstract is usually a brief summary of the content of the document.]Political ideologies (PIs) have existed since the dawn of human civilization; they have been challenged, discredited, addressed again and fought again. There are many available and have been tried for thousands of years. The question that torments humanity is always: how best to manage government affairs? It is best to understand that different political ideologies serve different purposes and that governments must remain ideologically flexible depending on current national conditions. All political ideologies proclaim themselves superior to all others; The fact is that all worldviews have specific flaws, merits, and goals. I will discuss the following political ideologies: Marxist/Communist, Leninist/Stalinist, Progressive/Socialist, Classical Liberalism/Capitalism, and Neoconservative. All of the IPs mentioned above have come to the forefront of this discussion because they have been the dominant forces since the Second Industrial Revolution or what we have come to understand as "modern times." These IPs in particular are well suited to modern times because of their focus on economics and power. Marxist/Communist theory originated as part of a sociological theory known as conflict theory. The theory developed by Karl Marx posits that there is a conflict between the ruling elite and the working class. Marx theorized that if the paper workplace posed them, the possibilities for innovation are endless. Success breeds success. Neo-conservatism while borrowing from classical liberalism and the international distribution of wealth in all regions of the globe, neo-conservatives want the whole world to be free and prosperous like them. The spread of economic freedoms also leads to social freedoms and the export of independence to all peoples. So we have looked at different political ideologies that have developed in modern times, but none of them proves superior to another. They all have certain strengths and weaknesses that all governments must take advantage of. It is best to understand that different political ideologies serve different purposes and that governments must remain ideologically flexible depending on current national conditions..
