How was Dmitry Rudin partly modeled on Mikhail Bakunin?

In his 1856 novel Rudin, Ivan Turgenev modeled the title character, Dmitry Rudin, partly on the revolutionary agitator Mikhail Bakunin, whom Turgenev had known in Moscow during the 1830s.12

The character of Rudin reflects specific traits associated with Bakunin, most notably his powerful gift for oratory and his passionate, vocal belief in the necessity of progress. In the novel, these qualities are so compelling that they captivate the younger members of a provincial salon, leading the heroine, Natalya, to fall in love with him. However, the characterization also highlights a significant flaw: when challenged to translate his eloquent words into action, Rudin fails to live up to his ideals, ultimately disappointing those who were inspired by him.12
