The Venezuelan crisis of 1895 occurred over Venezuela's longstanding dispute with Great Britain about the territory of Essequibo, which Britain believed was part of British Guiana and Venezuela recognized as its own Guayana Esequiba. The issue became more acute with the development of gold mining in the region.

As the dispute became a crisis, the key issue became Britain's refusal to include in the proposed international arbitration the territory east of the "Schomburgk Line", which a surveyor had drawn half-a-century earlier as a boundary between Venezuela and the former Dutch territory ceded by the Dutch in the Anglo-Dutch Treaty of 1814, later part of British Guiana.King (2007:249) The crisis ultimately saw Britain accept the United States' intervention in the dispute to force arbitration of the entire disputed territory, and tacitly accept the US right to intervene under the Monroe Doctrine. A tribunal convened in Paris in 1898 to decide the matter, and in 1899 awarded the bulk of the disputed territory to British Guiana.Graff, Henry F., Grover Cleveland (2002). . pp123-25

The dispute had become a diplomatic crisis in 1895 when a lobbyist for Venezuela William Lindsay Scruggs sought to argue that British behaviour over the issue violated the 1823 Monroe Doctrine and used his influence in Washington, DC, to pursue the matter. US President Grover Cleveland adopted a broad interpretation of the Doctrine that forbade new European colonies but also declared an American interest in any matter in the hemisphere.Zakaria, Fareed, From Wealth to Power (1999). Princeton University Press. . pp145–146 British Prime Minister Lord Salisbury and the British ambassador to Washington, Julian Pauncefote, misjudged the importance the American government placed on the dispute, prolonging the crisis before ultimately accepting the American demand for arbitrationPaul Gibb, "Unmasterly Inactivity?

By standing with a Latin American nation against European colonial powers, Cleveland improved relations with the United States' southern neighbors, but the cordial manner in which the negotiations were conducted also made for good relations with Britain.Nevins, Allan. Grover Cleveland: A Study in Courage (1932). ASIN B000PUX6KQ., 550, 633–648 However, by backing down in the face of a strong US declaration of a strong interpretation of the Monroe Doctrine, Britain tacitly accepted it, and the crisis thus provided a basis for the expansion of US interventionism in the Americas.Historian George Herring wrote that by failing to pursue the issue further the British "tacitly conceded the U. S. definition of the Monroe Doctrine and its hegemony in the hemisphere." Herring, George C., From Colony to Superpower: U.S. Foreign Relations Since 1776, (2008) pp. 307–308 Leading British historian Robert Arthur Humphreys later called the crisis "one of the most momentous episodes in the history of Anglo-American relations in general and of Anglo-American rivalries in Latin America in particular."

Background By 1895, the dispute between Britain and Venezuela over the territory of Guayana Esequiba, which Britain claimed as part of British Guiana and Venezuela saw as Venezuelan territory, had lasted for half a century. The territorial claims, originally those of the Spanish Empire, inherited by Venezuela after its independence in 1811, and of the Dutch Empire, inherited by the United Kingdom with the acquisition of the Dutch territories of Essequibo, Demerara and Berbice in 1814, had remained unsettled over previous centuries.Joseph, Cedric L. (1970), "The Venezuela-Guyana Boundary Arbitration of 1899: An Appraisal: Part I", Caribbean Studies, Vol. 10, No. 2 (Jul., 1970), pp. 56–89 Over the course of the 19th century, Britain and Venezuela had proved no more able to reach an agreement until matters came to a head in 1895, after seven years of severed diplomatic relations.

The basis of the discussions between Venezuela and the United Kingdom lay in Britain's advocacy of a particular division of the territory deriving from a mid-19th-century survey that it had commissioned. That survey originated with German naturalist Robert Schomburgk's four-year expedition for the Royal Geographical Society in 1835 to 1839, which resulted in a sketch of the territory with a line marking what he believed to be the western boundary claimed by the Dutch. He was thus commissioned by the British government to carry out a survey of Guiana's boundaries.R. A. Humphreys (1967), "Anglo-American Rivalries and the Venezuela Crisis of 1895", Presidential Address to the Royal Historical Society 10 December 1966, Transactions of the Royal Historical Society, 17: pp131-164 The result was the "Schomburgk Line", which he established partly to follow natural divisions and partly to distinguish territory of Spanish or Venezuelan occupation from that which had been occupied by the Dutch. The line went well beyond the area of British occupation and gave British Guiana control of the mouth of the Orinoco River.

In 1844, Venezuela declared the Essequibo River the dividing line; a British offer the same year to make major alterations to the line and cede the mouth of the Orinoco and much associated territory was ignored.Humphreys (1967:138) No treaty between Britain and Venezuela was reached until 1850 agreement not to encroach on disputed territory.

On 5 May 1859, Venezuela and Brazil signed a treaty to delimit their borders. It was agreed that the Orinoco and Essequibo river basins would be recognized as Venezuela's, while the Amazon river basin would be recognized as Brazil's.

The dispute went unmentioned for many years until gold was discovered in the region, which disrupted relations between the United Kingdom and Venezuela. In 1876, gold mines inhabited mainly by English-speaking people had been established in the Cuyuni basin, which was Venezuelan territory beyond the Schomburgk line but within the area Schomburgk thought Britain could claim. That year, Venezuela reiterated its claim up to the Essequibo River, to which the British responded with a counterclaim including the entire Cuyuni basin, although this was a paper claim the British never intended to pursue.

In 1886, Schomburgk's initial sketch, which had been published in 1840, was the only version of the "Schomburgk Line" published in British maps. That led to accusations by US President Grover Cleveland that the line had been extended "in some mysterious way".

In October 1886, Britain declared the line to be the provisional frontier of British Guiana, and in February 1887 Venezuela severed diplomatic relations. Proposals for a renewal of relations and settlement of the dispute failed repeatedly. By summer 1894, diplomatic relations had been severed for seven years, the dispute having dragged on for half a century. In addition, both sides had established police or military stations at key points in the area, partly to defend claims to the Caratal goldfield of the region's Yuruari basin, which was within Venezuelan territory but claimed by the British. The mine at El Callao, started in 1871, was once one of the richest in the world, and the goldfields as a whole saw over a million ounces exported between 1860 and 1883. The gold mining was dominated by immigrants from the British Isles and the British West Indies, giving an appearance of almost creating a British colony on Venezuelan territory.Humphreys (1967:139)

Venezuela had in the course of the dispute repeatedly appealed to the US and to the Monroe Doctrine, but the US government had declined to involve itself. That changed after Venezuela obtained the services of William Lindsay Scruggs. Scruggs, a former US ambassador to Colombia and Venezuela, was recruited in 1893 by the Venezuelan government to operate on its behalf in Washington D.C. as a lobbyist and legal attache. Scruggs had apparently resigned his ambassadorship to Venezuela in December 1892 but had been dismissed by the US for bribing the President of Venezuela. As a lobbyist, Scruggs published an October 1894 pamphlet, British Aggressions in Venezuela:, or the Monroe Doctrine on Trial in which he attacked "British aggression" and claimed that Venezuela was anxious to arbitrate over the Venezuela-British Guiana border dispute. Scruggs also claimed that British policies in the disputed territory violated the Monroe Doctrine of 1823. For much of the 19th century, it had only rarely been invoked by the United States, but a "paradigm shift in U.S. foreign relations in the late nineteenth century" saw Americans more actively support their increasingly-significant economic interests in Central and South America. The "'new diplomacy' thrust the United States more emphatically into the imperial struggle".Gilderhus, Mark T. (2006), "The Monroe Doctrine: Meanings and Implications", Presidential Studies Quarterly, Volume 36, Issue 1, pages 5–16 It was in that context that Scruggs sought to draw on the Doctrine in Venezuela's interests.

Crisis

Scruggs collaborated with Georgian compatriot Representative Leonidas Livingston to propose House of Representatives Resolution 252 to the third session of the 53rd United States Congress. The bill recommended Venezuela and the United Kingdom settle the dispute by arbitration. President Grover Cleveland signed it on 22 February 1895, after passing both houses of the United States Congress. The vote had been unanimous.Richard F. Hamilton (2010), America's New Empire: The 1890s and Beyond, Transaction Publishers, p. 131

On 27 April 1895, the Royal Navy occupied the Nicaraguan port of Corinto, after a number of British subjects, including the vice-consul, had been seized during disturbances, shortly after the former protectorate of the Mosquito Coast had been incorporated into Nicaragua. The British demanded an indemnity of £15,000. US Secretary of State Walter Q. Gresham thought the demands harsh, but also that they should be met. US public opinion, however, was outraged at the British military activity in the US sphere of influence.

In July 1895, new Secretary of State Richard Olney (succeeding Gresham, who died in office at the end of May) sent a document to London which became known as "Olney's twenty-inch gun" (the draft was 12,000 words long).Thomas Paterson, J. Garry Clifford, Shane J. Maddock (2009), American foreign relations: A history, to 1920. Cengage Learning. p. 205 The note reviewed the history of the Anglo-Venezuelan dispute and of the Monroe Doctrine, and it firmly insisted on the application of the Doctrine to the case, declaring that "today the United States is practically sovereign on this continent, and its fiat is law upon the subjects to which it confines its interposition."Humphreys (1967:150) The President, the Secretary of State, and the US public "had been brought to believe that Britain was in the wrong, that the vital interests of the United States were involved, and the United States must intervene." The note had little impact on the British government, partly because Joseph Chamberlain, at the Colonial Office, thought it possible that the colony had a major gold-bearing region around the Schomburgk line and partly because the British rejected the idea that the Monroe Doctrine had any relevance for the boundary dispute. A reply to Olney's note directly challenged his interpretation of the Monroe Doctrine:
