I'll give two Philippine examples:
- The EDSA People Power Revolution in the Philippines in 1986, notable for being nonviolent. From Wikipedia:
It "was a series of popular demonstrations in the Philippines, mostly in Metro Manila, from February 22–25, 1986. There was a sustained campaign of civil resistance against regime violence and electoral fraud. The nonviolent revolution led to the departure of Ferdinand Marcos, the end of his 20-year presidential term and the restoration of democracy in the Philippines."
...The People Power Revolution has inspired a call for a change of government through peaceful protests rather than bloodshed. Many similar revolutions have followed since then, taking the Philippine example of nonviolent regime change, such as that in East Germany and many other former Soviet Bloc countries. It also helped inspire the Arab Spring in 2011.
2. Jose Rizal (the Philippines' national hero) and his books "Noli Me Tangere" and "El Filibusterismo":
After publication, Noli me Tangere was considered to be one of the instruments that initiated Filipino nationalism leading to the 1896 Philippine Revolution. The novel did not only awaken sleeping Filipino awareness, but also established the grounds for aspiring to independence. Noli was originally written in Spanish, so the likelihood that Spanish authorities would read it first was very high; which is what Rizal wanted to happen. Copies of books were redirected to churches, many were destroyed, many anti-Noli writers came into the picture. Catholic leaders in the Philippines at the time regarded the book as heretical, while Spanish colonial authorities declared it as subversive and against the government. Underground copies were distributed, so Rizal decided to increase the price, the demand was so high.
The impact also included the expulsion of Rizal's clan in Calamba, Laguna. Extradition cases were filed against him. This led to his decision to write the sequel of Noli Me Tangere, the El filibusterismo. Unlike El Fili or Fili, as they called it, Noli Me Tangere was more delicate and did not invoke rebellion. as El Fili does. So to ensure revolutionary ideas and patriotic reaction, Rizal redefined his careful concepts in Noli to aggression in El Fili.
I'm not sure if people can attribute the 1896 Philippine Revolution as primarily caused by Rizal, but I think he did play a key role. I'm also unsure if we should label the revolution a success (since the revolution merely transferred rule of the Philippines from the Spanish to Americans, and it's not clear to me if the Philippines played a large role in that happening), but I think these 2 books show the capability of fiction/books to inspire revolutions.
Neither of these examples involve movements on the approximate scale of EA. Both seem quite beneficial though and had some attention to detail (i.e. focused on being nonviolent).
I'm not sure if there are any strong Philippine examples that involve movements on the scale of EA, but maybe the work of various local advocacy groups to have the Philippine Mental Health Act passed in 2018 could be one. Though those groups combined could be smaller than the current scale of EA.
