The Harry Potter Alliance is a community of an army of fans, activists, nerdfighters, teenagers, wizards and muggles whose goal it is to decrease worldsuck.

They are like the real life Dumbledore's Army. The same way the DA fights Death Eaters, the HPA fights poverty and global warming.

A charitable organization focused on fighting for human rights and social justice using the most powerful weapon we have: love. Thanks to the help of Nerdfighteria, they were the recipient of the 2010 Chase Community Giving grant of $250,000.
