Kharkiv, Ukraine's second-largest city, lies in the northeastern part of the country and serves as the administrative center of Kharkiv Oblast. Founded in 1654, it has evolved into a significant hub for industry, trade, and Ukrainian culture within the historic region of Sloboda Ukraine. During the 2022 Russian invasion of Ukraine, Kharkiv became a strategic focal point due to its proximity to the Russian border, experiencing battles and bombardments that highlighted its importance in the broader geopolitical landscape. The city's resilience and response to the conflict have underscored its critical role in Ukraine's defense and national identity.
