In the end, the protocol brought together the two previous appointments in a single succession plan which envisaged al-Amin as the first successor to the caliphate and al-Mamun as the second with full guarantee. The full guarantee meant that al-Amin could not remove his brother from the line of succession in any form. The Mecca Protocol of 802 has now completely changed after the death of Harun al-Rashid.
