On page 217 in his chapter on "Saddleback Church and the Montgomery Bus Boycott," Charles Duhigg explains in The Power of Habit
A movement starts because of social habits of friendship and the strong ties between close acquaintances.
It grows because of the habits of a community, and the weak ties that hold neighborhoods and clans together.
And it endures because a movement's leaders give participants new habits that create a fresh sense of identity and ownership.
He refers to this as "a three-part process that historians and sociologists say shows up again and again".
