The Balfour Declaration was actually a letter dated November 2, 1917 letter written by the Foreign Secretary of the United Kingdom, Arthur Balfour, Walter Rothschild, 2nd Baron de Rothchild and leader of the Jewish community in Britain in order to be transmitted to the Zionist Federation of Great Britain and Ireland.
The text of the letter was published a week later, on November 9, 1917 with the title "Balfour Declaration", which was later incorporated into the Treaty of Sevres with the Turkish Ottoman Empire and the mandate was Britain on Palestine.
The text was approved by the US government previously.
The Balfour Declaration became the Mandate of Great Britain's Partitioning Plan for the Middle East land that had been defined as Palestine.
Although the publication of the text was scheduled for Christmas because it was assumed that by that time had already been taken fully into Palestine, he managed to slip to the press.
