Which two countries were Britain's main competitors in naval battleships during the late 19th century?

During the late 19th century, Britain's primary naval competitors were France and Russia. This period was marked by significant naval arms races, particularly influenced by the two countries' efforts to expand their fleets in response to Britain's superior naval power.

France was successful in modernizing its navy and building ironclad warships, aiming to challenge British dominance at sea. The Franco-British naval rivalry was particularly pronounced, as both nations sought to assert their influence through naval strength.

Meanwhile, Russia was engaged in a massive naval expansion, especially after the establishment of the Russo-Japanese War in 1904, which emphasized the importance of a strong naval presence for global power status. The competition between these countries not only propelled advances in shipbuilding and naval tactics but also laid the groundwork for strategic alliances and rivalries that would shape international relations in the early 20th century.

This context reveals why France and Russia stand out as Britain's main competitors in this period, setting them apart from other military nations that did not have the same level of naval focus or rivalry with Britain.
