By forming various organizations.
The European Union, for example, unites Europe (Minus Britain these days) under one banner, thus preventing fighting.
A more direct example is the North Atlantic Treaty Organization. NATO protects the "North Atlantic" and Europe from terrorists and invading countries by using the combined military strength of multiple nations.
The Tower of London was built in the year 1078 by King William, Duke of Normandy.
This Tower is more than 1000 years old and is the oldest palace, fortress and prison in Europe. History tells us that King Edward of England failed to keep a promise to give his throne to William, Duke of Normandy but instead gave it to Harold Godwinson, his English brother in law.
William became angry and sent his army across the English channel to conquer England and on October 14, 1066 he fought with Harold and won the battle. Later that year on Christmas day, William was crowned King.
To keep the unruly citizens of London in line, he decided he needed a stronghold and so he built the Tower to act as his fortress.
With time, other smaller towers, extra buildings, walls, and walkways were added gradually transforming the original building into the splendid example of castle, fortress, prison, palace and finally museum that we enjoy today.
The Tower of London is a tourists attraction today.

My opinion is that it is fair that the Jewish People have a place to claim as their own, that is also their ancestral land, since they have been an errand people since the times of the Roman Empire, who have been expelled from many countries, and who have been subject to discrimination and poor treament.
However, it would also be fair that the Palestian Arabs have a share of the land too, because they were dwelling those land for more than a millenium before the Jewish began to settle back. This is why the most reasonable policy for the area would be a two state solution: one state for the Jewish People, and one state for the Palestinian Arabs.
The development of agriculture occur circa around 8000-6000 years ago. It was a time where many nomadc population begin to settle in a place, thus effectively starting the civilization as we know now. it was a huge shift for humanity and it was probably one of the most important, if not the most important achievement in human history.
It was quickly accepted as the preferred food source by people living in settlements because it could be planned and organized, thus helping people reaching a balance easily and preventing them from being dependent from the results of hunt and gathering. it was a safe and sicure way to assure food for everyone.
