the strongest wizard of the modern era

In the Harry Potter series, Albus Dumbledore was considered the strongest wizard. His knowledge and power of magic were second to none. He had been the headmaster of Hogwarts School of Witchcraft and Wizardry, and had been a Transfiguration teacher for many years. In his duel with Voldemort at the Ministry of Magic, he had displayed profound Transfiguration and the elegant art of dueling. Even the most powerful Dark Lord in history, Voldemort, was afraid to face him head-on. But there were other powerful wizards, such as Tom Riddle (Voldemort), the most powerful Dark Lord in history, the creator of seven Horcruxes, a Parseltongue, and one of the few who could fly without a broom, who could fight Dumbledore for a long time without losing. Gellert Grindelwald almost destroyed Paris with his demonic fire and was strong enough to challenge Dumbledore in a duel. Severus Snape was the most powerful Occlumency Master in the world, proficient in Defense Against the Dark Arts and potions, able to create his own spells and potions, and possessed a unique ability to fly. And Minerva McGonagall, one of the most powerful witches of her time, was a powerful shapeshifter and an Animagus. Felius Flevy had been a former dueling champion who had defeated the Death Eater Antonin Dolohov and had created a powerful armor amulet for the final battle. Each of these wizards had their own strengths, but overall, Dumbledore was usually seen as the strongest. Harry Potter and the Chamber of Secrets is not enough.
