The colonies of Fiji and New Zealand were originally part of this process, but they decided not to join the federation. Following federation, the six colonies that united to form the Commonwealth of Australia as states kept the systems of government that they had developed as separate colonies, but they also agreed to have a federal government that was responsible for matters concerning the whole nation. When the Constitution of Australia came into force, on 1 January 1901, the colonies collectively became states of the Commonwealth of Australia.

Union of Brittany and FranceW
Union of Brittany and France

The union of Brittany and France was a critical step in the formation of modern-day France. Brittany had been a semi-independent component of the Kingdom of France since Clovis I was given authority over the Gallo-Roman domain during the 5th century. It was first recorded as a "duchy" during the rule of Nominoe in 846. Over the centuries, the fealty demonstrated by the Duchy of Brittany toward the French king depended significantly on the individuals holding the two titles, as well as the involvement of the English monarchy at that particular time. The reign of Francis II, Duke of Brittany, was at an especially crucial time, as the nobles struggled to maintain their autonomy against the increasing central authority desired by Louis XI of France. As a result of several wars, treaties, and papal decisions, Brittany was united with France through the eventual marriage of Louis XI's son Charles VIII to the heiress of Brittany, Anne in 1491. However, because of the different systems of inheritance between the two realms, the crown and the duchy were not held by the same hereditary claimant until the reign of Henry II, beginning 1547.

Bulgarian unificationW
Bulgarian unification

The Unification of Bulgaria was the act of unification of the Principality of Bulgaria and the province of Eastern Rumelia in the autumn of 1885. It was co-ordinated by the Bulgarian Secret Central Revolutionary Committee (BSCRC). Both had been parts of the Ottoman Empire, but the Principality had functioned de facto independently whilst the Rumelian province was autonomous and had an Ottoman presence. The Unification was accomplished after revolts in Eastern Rumelian towns, followed by a coup on 18 September [O.S. 6 September] 1885 supported by the Bulgarian Knyaz Alexander I. The BSCRC, formed by Zahari Stoyanov, began actively popularizing the idea of unification by means of the press and public demonstrations in the spring of 1885.

Canadian ConfederationW
Canadian Confederation

Upon confederation, what had formerly been called the Province of Canada was divided into the two provinces of Ontario and Quebec. Thus, the new Dominion initially consisted of four provinces, including the provinces of Nova Scotia and New Brunswick. Over the years since Confederation, Canada has seen numerous territorial changes and expansions, resulting in the current number of ten provinces and three territories.

At present, the island is divided politically; the sovereign Republic of Ireland has jurisdiction over the majority of Ireland, while Northern Ireland, which lies entirely within Ulster, is part of the United Kingdom. Achieving a united Ireland is a central tenet of Irish nationalism, particularly of both mainstream and dissident Irish republican political and paramilitary organisations. Unionists support Northern Ireland remaining part of the United Kingdom, and therefore oppose Irish unification.

The convention led to the adoption of the South Africa Act by the British Parliament and thus to the creation of the Union of South Africa. The four colonies of the area that would become South Africa - the Cape Colony, Natal Colony, the Orange River Colony and the Transvaal Colony - were represented at the convention, along with a delegation from Rhodesia. There were 33 delegates in total, with the Cape being represented by 12, the Transvaal eight, the Orange River five, Natal five, and Rhodesia three. The convention was held behind closed doors, in the fear that a public affair would lead delegates to refuse compromising on contentious areas of disagreement. All the delegates were white men, a third of them were farmers, ten were lawyers, and some were academics. Two-thirds had fought on either side of the Second Boer War.

Unification of Romania and MoldovaW
Unification of Romania and Moldova

The unification of Romania and Moldova is a popular concept in the two countries beginning with the late 1980s, during the collapse of communism. The Romanian Revolution in 1989 and the independence of Moldova in 1991 further contributed to the development of a movement for the unification of the two Romanian-speaking countries. The question of reunification is recurrent in the public sphere of the two countries, often as a speculation, both as a goal and a danger. Most of Romania supports unification, but a majority of Moldova continues to oppose it. However, support in Moldova for reunification has increased significantly, with polls asking "if a referendum took place next Sunday regarding the unification of the Republic of Moldova and Romania, would you vote for or against the unification?" rising from approximately 20% to 40% support from 2015 to 2021. Support for unification is much lower in Transnistria and Gagauzia than in the rest of Moldova.

The Samoan people in both countries share ethnicity and culture. But their islands have remained politically separated. The western islands were incorporated as the Western Samoa Trust Territory under British administration from 1920–1946, and under New Zealand administration from 1946 to 1962. The Inter-Samoan Consultative Committee was established in 1955 to promote cooperation between the two. Richard Barrett Lowe, the governor of American Samoa from 1953 to 1956, said during his tenure that it had been decided that reunification with Western Samoa was not to be discussed by the Committee.
