What adventures does Don Juan experience in Lord Byron’s poem?

In Lord Byron’s Don Juan, the protagonist is reimagined not as a legendary libertine, but as an innocent young man who serves as a rational observer of the world's absurdities. His adventures include:1

• Exile and Shipwreck: After being sent away from his home in Sevilla by his mother, Juan survives a shipwreck.1
• Slavery and Escape: Following the wreck, he is cast onto a Greek island and subsequently sold into slavery in Constantinople, from which he eventually escapes.1
• Military Service: He joins the Russian army and displays gallantry during the siege of Ismail.1
• Diplomatic Mission: After arriving in St. Petersburg, he earns the favor of Catherine the Great, who dispatches him on a diplomatic mission to England.1

Throughout these travels, Juan frequently succumbs to the advances of women, though the poem primarily functions as a picaresque vehicle for Byron’s satirical commentary on social hypocrisy and human pretension.1
