It all seemed to start quite innocently really. After nearly three generations of fear and worry, the wizarding world was ready for peace. The long arduous task of recovery and rebuilding began, and the people elected Amos Diggory to the post of Minister of Magic by a landslide. They saw a stable future in the promises of the man who lost his only son as one of the first casualties of the second war. He was charismatic and persuasive, used strongly worded speeches and cleverly hidden reminders about his son to secure his place in the Ministry.
He sought justice, and the public responded well to the new laws that were to make the country safer. The ex-Death Eaters were first, their freedoms taken, labelled suspected terrorists. Their family members were next, then all purebloods. The suspected terrorists were branded. Now, wands are monitored, there are curfews, tracking charms and interrogations. The Ministry has almost total control.
But there is a resistance. They may be small, but they're fighting back.
