Law has always played an important role in humans and their daily lives. Laws have always been different region to region, but throughout history it has kept evolving in all sorts of ways while reflecting the current socio political issues and the current values of society. The ancient Egyptians had a civil code that was stretched into twelve books back in 3000BC. It outlined laws for equality among the social class, tradition and other important issues. Fast forwarding a couple of ages later the Sumerians came up with the first ever law code which had many casuistic conditions. The Babylonians took it a step further and wrote down laws on stone and distributed this all over the country for the public to read and view.
The ancient Greeks were the ones who first started up the practice of lawyers. The Greeks had a rule that any one accused of a crime will have to defend themselves on their case but as time went on, it turned into the particular person asking a friend for help.
After a while noticing the market for this, some people studied the system and offered their services to argue on behalf of the defendant. This is thought to be the beginning. History suggests that the first ever lawyers were the orators in Rome who took the Greek system a step further. The ancient Indians and the Chinese had schools that taught students the legal system and encouraged them to practice. They have many books and texts that gave important legal advice and guidance which were written all the way back in 100BCE. But after the British Empire set its foot in the country and made India a part of the empire, the common law replaced the ancient laws they country had. Japan is considered to be one of the first countries in the East to implement parts of the Western law in their legal system. They are thought to have used the German laws and codes to help them develop themselves. In the exact same fashion the Chinese gave up on their traditional outlook of law to adopt a similar western law and outlook.
In the Europe the French and the Germans are credited with making great strides on the movement for better laws and regulations for solicitors at Sutherland. It was during this era that the English came up with their own type of common law. This same law was followed in the Americas, but certain parts of the continent, especially countries like Mexico instead followed the Spanish law or the French legal system.
