Final answer:
In 1905, Norway dissolved its union with Sweden and became an independent kingdom.
Step-by-step explanation:
The country that dissolved its union with Sweden in 1905 is Norway. The dissolution of the union on June 7, 1905, allowed Norway to become an independent kingdom under its own sovereign rule, after being in union with Sweden since 1814. This historic event is significant as it marked the peaceful secession of Norway from Sweden and the establishment of Norway as an independent entity in the international community.This separation was the result of a negotiated agreement between Norway and Sweden, and it marked the end of the Union between the two countries, which had been in place since 1814. Following the dissolution, Norway became a fully sovereign and independent nation.
