Over time these terms acquired distinct connotations leading to the present difference in definition. An example of this is the United States under the Articles of Confederation. The Articles established a national government under what today would be defined as a federal system (albeit with a comparatively weaker federal government). However, Canadians, designed with a "stronger" central government than the U.S. in the wake of the Civil War of the latter, use the term "Confederation" to refer to the formation or joining, not the structure, of Canada. Legal reforms, court rulings, and political compromises have "decentralized" Canada in practice since its formation in 1867.
