1st Answer:
They didn't and they worked pretty much hand in hand. It wasn't until the late 1300's and the 1400's that there was any problems. If you are thinking of Henry VIII, he isn't in the middle ages. He was much later.
2nd Answer:
There were many clashes between religious authorities and political rulers during the Middle Ages, including the Investiture Controversy in the 11th and 12th centuries, the events surrounding the Great Schism of the West in the 14th and 15th centuries, the events surrounding the death of Thomas Becket in 1190, and a number of others. They started early on, under the Roman Empire, in fact, and never really disappeared.
These problems were all about power. The kings and emperors wanted to be able to appoint bishops who would do their bidding; the bishops and popes wanted to keep monarchs out of Church business. The clergy had rights the Church wanted to protect, such as the benefits of clergy, which meant that clergy who got into trouble with the law were tried by the Church instead of the state; the kings wanted the Church out of their business. The kings were limited in their taxation because the Church controlled a large amount of wealth, but was exempt from taxation in many places; the Church wanted to stay tax free. There were a number of other issues, but it all boiled down to a question of power, keeping power, or gaining power.

Political leaders, kings and emperors, wanted to control the Church in their own lands, and to that end tried to control who was to be appointed to be bishops within their lands. The Church opposed this as not a right for the rulers, and the result was what is called the Investiture Controversy.

Monarchs often demanded that they be chosen as pope.

From 1854-1861, a variety of conflicts, referred to as 'Bleeding Kansas,' occurred in the territory (and soon-to-be state) of Kansas between pro-slavery and anti-slavery Americans. These conflicts had the general effect of adding to national tensions between the South and the North and may be said to have contributed to the outbreak of the American Civil War.

Roman Catholic AnswerFor the main part, conflicts between protestants and Catholics have been more conflicts between different peoples who happen to be Catholic or protestant. For instance, in Ireland, the Irish, who were fighting to save their nation, all happened to be Catholic, while the English were all protestant. Other conflicts have come about because of ignorance and/or intolerance. For the most part protestants have been brought up to believe that Catholics are not Christian and are worse than pagans. This has been very unfortunate, with disastrous results in some cases. I, myself, was brought up in a protestant household and Catholic beliefs were beyond the pale. I have heard that everbody was warned at my parents wedding to not tell my mother's grandmother that the bridegroom's mother was Catholic. All very sad.
