Prepositions that follow ''Abnigate'

In this sentence "After a short reign Shah Shuja was compelled to abdicate from his inability to repress the rising power of Fateh Khan, a Barakzai chief, and he took refuge first with Ranjit Singh, who then ruled the Punjab, and finally secured the protection of British power."

What does the underlined part indicate? Was he compelled to abdicate because of his inability to repress? Is that what this line indicates?If yes? Can we use 'because' as a replacement.?

One more thing.I know 'as' and 'from' goes after the word 'Abdicate'.Can anyone tell what other prepositions come after Abdicate??
