The Turkey Hundred Years Agreement, also known as the Sykes-Picot Agreement, was a secret treaty signed between France and the United Kingdom during World War I. The treaty aimed to divide the Middle East between the two powers by redrawing the borders of the Ottoman Empire.

The agreement was signed on May 16, 1916, and was named after its architects, Sir Mark Sykes of the UK and François Georges-Picot of France. The treaty divided the Ottoman Empire`s territories into spheres of influence for France and the UK, with Russia also being promised territories in the region.

The treaty has been described as the main cause of the current instability in the Middle East. It created borders that did not take into account the diverse ethnic and religious groups in the region, leading to the creation of artificial states that have been unable to provide stability and security for their citizens.

The agreement caused resentment among the Arab population, as it denied them the opportunity to create their own states based on their shared history and cultural heritage. Instead, the region was carved up based on the interests of European powers.

The treaty was superseded by the Treaty of Sèvres in 1920, which redrawn the borders of the Ottoman Empire and led to the creation of modern-day Turkey. However, its legacy still lives on, with many of the problems in the Middle East today being traced back to the Sykes-Picot Agreement.

Today, the Middle East is still grappling with the legacy of the Sykes-Picot Agreement. Many of the borders created by the agreement have been contested and fought over, with groups such as ISIS seeking to redraw them entirely.

In conclusion, the Turkey Hundred Years Agreement, or Sykes-Picot Agreement, was a secret treaty signed between France and the United Kingdom during World War I that aimed to divide the Middle East between the two powers. Its legacy can still be seen in the region today, and it is often cited as a cause of the current instability in the Middle East.
