The British North America Acts 18671975 are a series of Acts of Parliament that were at the core of the constitution of Canada. Most were enacted by the Parliament of the United Kingdom and some by the Parliament of Canada. In Canada, some of the Acts were repealed in Canada by the Constitution Act, 1982. The rest were renamed the Constitution Acts and amended, with those changes only having effect in Canada. The Canadian versions of the Constitution Acts make up the Constitution of Canada, and can only be amended in Canada.

The British versions of the Acts which remain in force in Britain are ordinary British statutes. They can be amended by the British Parliament, but those amendments would not have any effect in Canada. They retain their original names and do not include any amendments made in Canada since 1982.

The term "British North America" (BNA) refers to the British colonies in North America, after 1783.

Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death in 1901. Known as the Victorian era, her reign of 63 years and seven months was longer than any previous British monarch. It was a period of industrial, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire. In 1876, the British Parliament voted to grant her the additional title of Empress of India.

Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn (the fourth son of King George III), and Princess Victoria of Saxe-Coburg-Saalfeld. After the deaths of her father and grandfather in 1820, she was raised under close supervision by her mother and her comptroller, John Conroy. She inherited the throne aged 18 after her father's three elder brothers died without surviving legitimate issue. Though a constitutional monarch, Victoria privately attempted to influence government policy and ministerial appointments; publicly, she became a national icon who was identified with strict standards of personal morality.

Victoria married her first cousin Prince Albert of Saxe-Coburg and Gotha in 1840. Their children married into royal and noble families across the continent, earning Victoria the sobriquet "the grandmother of Europe" and spreading haemophilia in European royalty. After Albert's death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result of her seclusion, British republicanism temporarily gained strength, but in the latter half of her reign, her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration. She died on the Isle of Wight in 1901. The last British monarch of the House of Hanover, she was succeeded by her son Edward VII of the House of Saxe-Coburg and Gotha.
