History behind Book of Galatians

Almost every book that is written has a history behind it, like someone is writing a book on English language, so he wants people to know about English or he wants people to learn different things regarding English language. Same as this if somebody writes a book on a personality so his motive can be taken as the fame of the personality or he may be taking that personality as an example for many people.
Same as this the book of Galatians also has some reasons behind it. Galatia was a part of a country which is now known as Turkey. A lot of the people living there were Gentiles. Paul paid visits to the province at least two times. Many people became Christians as he preached the good news about Jesus. Paul was weak when he first preached the people but people were much exited to hear his message. Once the people were converting in to Christians, some of the false Jewish teachers visited them. Those Jewish teachers were jealous of Paul and spoke against him. They tried to change people`s mind again and said that Paul is not an apostle and also said that Christians had to obey Jewish laws. These laws would control the people, some of the Galatians believed those false teachers. When Paul came to know this, he was very much worried about this situation. He thought to remind them the real liberty that Jesus gives so he wrote a letter to Galatians to teach them the truth again.
It was never easy for Paul to remind the Christians about the truth behind liberty in Christianity so Paul was trying to write something which attracts people easily and he could deliver his message of sincerity that belief can achieve all which laws can never, easily
