During the Civil War, the Monroe Doctrine's emphasis on opposing European intervention in the Americas reinforced U.S. claims to sovereignty and territorial integrity. While the United States was embroiled in internal conflict, the doctrine served as a diplomatic tool to prevent European powers from recognizing or supporting the Confederacy. This helped to ensure that foreign nations remained neutral, bolstering the Union's efforts to maintain its unity and ultimately contributing to its victory. The doctrine underscored the emergence of the U.S. as a self-proclaimed protector of the Western Hemisphere.
ANSWER The France.
The Monroe Doctrine covered the Western Hemisphere. At the time, Great Britain applauded this doctrine in that it then considered its North American holdings, such as Canada, safe. Violations did occur however and were treated not specifically to be Monroe Doctrine ones. By this I mean the installation of a French puppet regime in Mexico. After the US Civil War, assembling US troops on the Mexican border, and threatening to invade Mexico was enough for France to abandon this idea. Regardless of the Doctrine, the US used its military to protect its own national security.
During the time before the Civil War, free soil doctrine was to not have slavery in any new states admitted into the Union.
Perhaps the most important issue behind the Monroe Doctrine was a fear that Spain would reassert its claims on parts of Latin America that had become independent. The idea of opposing this had been suggested to the Americans by the British government. But the immediate cause was statements by the Russian government asserting its claims on the territory of Alaska and the ocean approaches to it, to a distance of a hundred miles.

Definition of Monroe DoctrineJust to be clear, the Monroe Doctrine was a statement made by US President James Monroe in 1823 that effectively stated several things: (1) that new attempts by European nations to create new colonies or re-colonize newly independent states in the New World would be viewed negatively by the US, (2) that the US would intervene in any such conflict, and (3) that the European nations were free to maintain current colonies and internal affairs without the US meddling with those.Most European countries laughed at the US for proposing this because the US had no means of effectively fighting against them. It was Britain's support for the Monroe Doctrine that made the Doctrine more-or-less followed.Concerning FriendshipThe cordial relations between the US and UK in 1823 had no bearing on Europe's response to the Monroe Doctrine. The US and UK would only truly become "friends" in the later 19th century after the US Civil War. However, the Monroe Doctrine is often see as a precursor to the "US-UK Special-Relationship" which was well-established in the 20th and 21st centuries.Since "friendship" did not really exist between the US and UK in 1823, the presence or lack of friendship was IRRELEVANT in determining Europe's leaders' responses to the Monroe Doctrine.Actual Reason for SuccessWhat Britain did that made the Monroe Doctrine successful was their Foreign Secretary George Canning's statements that the British Navy would enforce and defend the Americas from European intervention along the lines stated in the Monroe Doctrine. Because Britain was the most powerful country in the world, as opposed to the US, which was relatively weak, the British approval was critical and lead to the Europeans acquiescing to the terms of the Monroe Doctrine.If Britain had not supported the Monroe Doctrine (or actively opposed it), it would have been a worthless speech. European Powers that had recently lost colonies in the New World, like Spain and Portugal, would likely have attempted to reclaim those territories. Other European Powers would try to conquer recently independent countries, like France actually did when Napoleon III decided to invade Mexico in 1861 because the US Civil War prevented direct US intervention to protect Mexico. Others would want to extend their current colonies, such as Russia had tried in the Ukase in 1821.

The Monroe Doctrine was a policy of the United States. It was introduced on December 2, 1823. The declaration stated that any efforts by European nations to colonize land or interfere with states in North or South America would be considered acts of aggression, requiring the United States to intervene. It also stated that the United States may not interfere with existing European colonies nor is the United States allowed to get involved with the concerns of European countries. The Monroe Doctrine was issued at a time where all Latin American colonies of Spain and Portugal had achieved or were at the point or achieving independence from the Portuguese Empire and Spanish Empire. The president, James Monroe, first stated the Monroe Doctrine during his seventh annual State of the Union Address to Congress. The declaration gained its name in the year 1850. By the end of the nineteenth century, Monroe's declaration was seen as a defining moment in the foreign policy of the United States. The Monroe Doctrine's primary cause was to free the newly independent colonies of Latin America from the intervention or Europe and avoid situations which could lead to the New World becoming a battleground for the Old World's powers. The Monroe Doctrine didn't play a roll in the civil was and wasn't of much importance then.
During the time before the Civil War, free soil doctrine was to not have slavery in any new states admitted into the Union.

In 1863, with the United States engaged in its Civil War, the French, under the rule of Napoleon III invaded Mexico and enthroned their puppet, the Hapsburg Maximilian. This of course violated the Monroe Doctrine, but that had already been violated by the British with their policies with the Republic of Texas and their ideas about the US West coast. Nevertheless, when the US Civil War ended, the US placed an army on the Mexican border and ordered the French to withdraw. Napoleon III removed his troops. Maximilian remained, was captured by Mexican troops and was executed.
