The state border was fairly open until the 1920s. Culture and trade formed lively connections across the border, creating rich traditions. Even though the lifestyles of the Kainuu people, who had withdrawn to wooded hills, and Viena Karelian people, who lived in villages, were different, many customs, stories and work skills were the same. Marriages across the border were also common. Over the past few decades, there have been more connections again.
