First of all you have to understand the two key words 'political' and 'thought'. The word political is derived from the word politics. Politics is gotten from three Greek words Polis meaning the City -state, Polity meaning government and politia meaning constitution. Examining these three the entirety of the concept of political simply denotes focusing on the Polis( the organization of the Anicent Greeks which can be likened to the modern day state or country) and its component parts as well as their functions. The term political refers to anything public or for the totality of the polis. Therefore Political thought can be defined as the thought of the state as it ought to be and function. It is concerned also with the behavioural pattern, involvement and rendition of the people as regards the issue of state affairs in the Polis.
A political thought is also known as ?political philosophy.? This is the study of the concepts of politics, what they are, why they?re necessary, what makes them legitimate. You can learn more about this at http://en.wikipedia.org/wiki/Political_thought
