Multiple sources state that Hetman Ivan Mazepa abandoned Peter I and joined Charles XII's Swedish forces in October-November 1708, during the Russo-Swedish phase of the Great Northern War. The claim's wording matches the post and the sources, and the sources use 'Second Northern War' and 'Great Northern War' as the broader name for the same conflict.

What was said

… So, um, so even, even pro-Russian, uh, now the only reason that the Poles were slightly more reasonable is because they were much weaker.

What we found

Supports. Harvard Ukrainian Studies describes Mazepa abandoning Peter I to join the Swedish invaders on 26 October 1708, at the height of the Great Northern War.[1]

Supports. Britannica states that Mazepa and about 5,000 Cossacks joined the Swedes instead of aiding the Russians in October 1708, after entering secret negotiations with Charles XII when the Second Northern War began.[2]

Supports. Wikipedia and EBSCO both say Mazepa abandoned his alliance with Peter I and sided with Sweden's Charles XII in 1708, during the Great Northern War.[3][4]

Supports. The Encyclopedia.com entry describes Mazepa's secret dealings with Sweden and his move to join Charles XII when Sweden invaded Russia in 1708.[5]

Context. The Russo-Swedish War is part of the Great Northern War (1700-1721); the sources treat the 1708 defection as occurring within that war, so the claim's label is a standard alternative name rather than a contradiction.[1][2]

Context. The sources differ on framing (treason versus justified defection), but none disputes that the defection to the Swedes happened.[1][6]
