The Unbroken Vow: Dumbledore and Grindelwald's Pact Explained

Have you ever wondered why Dumbledore couldn't confront Grindelwald from the start? It's peculiar that Dumbledore waited for so long to face him eventually and triumph over him, ending his reign of terror. What's the reason behind all this waiting?

It all began when friends Dumbledore and Grindelwald joined forces, each with their own goals. Grindelwald aimed for supremacy, seeking to possess magical artifacts and control the world. On the contrary, Dumbledore sought to halt Grindelwald's dominance over the magical world. However, there was always a reason restraining him, a reason he couldn't overcome.

The reason lies in the Blood Pact, a magical contract that binds the parties involved, creating a magical bond by sharing their blood. The Blood Pact is made by cutting the parties' hands, intertwining them, and performing the required vow. Two glowing drops of their blood rise and merge, forming a vial to contain the Blood Pact. Once created, breaking and destroying the vial becomes seemingly impossible.

Grindelwald and Albus Dumbledore used this pact during their teenage years, swearing never to harm each other. Grindelwald kept the vial, making it nearly impossible for Dumbledore to defeat him.

The Blood Pact was finally broken when Albus Dumbledore and Aberforth Dumbledore united to protect Credence (Aurelius Dumbledore) from Grindelwald's killing curse. Dumbledore and Grindelwald had not considered the consequences of their conflicting desires, leading to the demise of the Blood Pact and Dumbledore's victory over Grindelwald.
