MDCCXXIII

MDCCXXIII is the Roman numeral that represents the number 1723. It is formed by the symbols M (1000), D (500), CC (200), XX (20), and III (3). The value is obtained by adding these components, so MDCCXXIII equals 1000 + 500 + 200 + 20 + 3.

In calendar terms, MDCCXXIII denotes the year 1723 in the Gregorian calendar. By that time, most of Europe had adopted the Gregorian system, though some regions still used the Julian calendar, leading to potential differences in date alignment. The year falls within the early 18th century, a period of continuing European monarchies such as George I of Great Britain (reign 1714–1727) and Louis XV of France (reign 1715–1774). In East Asia, the Yongzheng Emperor was ruling in the Qing Dynasty, having begun his reign in 1722. In the Catholic Church, Pope Innocent XIII presided from 1721 to 1724.

Historically, 1723 sits within the broader era of the Enlightenment, characterized by scientific inquiry, philosophical discourse, and expanding global trade and colonial administration. As with many years, MDCCXXIII appears on inscriptions, regnal lists, and archival documents used to denote events and periods associated with that year. The numeral itself remains a conventional notation for dating historical material and is frequently encountered in manuscripts, architectural inscriptions, and commemorative objects from or about the early 18th century.
