19. Royal authority results from superiority
Royal authority results from superiority. Superiority results from group feeling. Only by God’s help in establishing His religion do individuals desires come together in agreement to press their claims, and hearts become united (The Muqaddimah 3.125).

20. …The power (of the ruling dynasty) is then wiped out
…The power (of the ruling dynasty) is then wiped out. Superiority exists merely in proportion to (the existing) group feeling, without the additional (power of ) religion. As a result, the dynasty is overpowered by those groups (up to this time) under its control, that are equal or superior to it in strength. It had formerly overpowered the groups that had a stronger group feeling and were more deeply rooted in desert life, with the help of the additional power that religion had given it… (The Muqaddimah 3: 126)

21. Similarly, prophets in their religious propaganda depended on groups and families, though they were the ones who could have been supported by God with anything in existence, if He had wished, but in His wisdom He permitted matters to take their customary course. (The Muqaddimah 3: 127)

22. Each dynasty depended on the numerical strength of its supporters
Each dynasty depended on the numerical strength of its supporters. When its numbers were exhausted through expansion, no further conquest or extension of power was possible. This is how God proceeds with His creatures. (The Muqaddimah 3: 129)

23. People lose the good qualities that were a sign and indication of royal authority. They adopt the contrary bad qualities. This points toward retrogression and ruin, according to the way God (has planned) for His creatures in this connection. The dynasty shows symptoms of dissolution and disintegration. (The Muqaddimah 3: 135)
