This is the board that Mirza Ghulam Ahmad formed in his lifetime ( in his book The Will) to oversee the affairs of the Heavenly Graveyard. Its formation was similar to the board of a corporation, and it came to handle the financial affairs of the Ahmadiyya.
After the death of Mirza Ghulam Ahmad, the board was headed by Hakeem Nooruddin, and subsequently by Maulana Muhammad Ali.
On the death of Hakeem Nooruddin, Mirza Mahmud Ahmad, a member of the board and one of the sons of Mirza Ghulam Ahmad, stated that the authority of Hakeem Nooruddin was personal, and not in his capacity as the chairman of this board. He claimed successorship to that personal authority as Khalifa. Followers of the incumbent chairman, Maulana Muhammad Ali, disagreed, and formed the Lahori Ahmadiyya group.
Mirza Mahmud Ahmad made many changes to the board and its powers, and today it exists only as a rubber-stamping administrative organization.
The Lahori group has its own board with the same name.
On the foundation of Pakistan, a third board with the same name was incorporated in Pakistan.
