1748 was a mid‑18th‑century year notable for diplomatic settlement, intellectual publication, and ongoing colonial rivalry. In Europe the long-running War of the Austrian Succession drew to a formal close, while thinkers and mathematicians issued works that shaped later political and scientific debate. The year sits squarely in the era historians call the Enlightenment and reflects both the practical bargaining of great‑power politics and a flourishing of ideas.
Politics and war
The principal political event of 1748 was the negotiation and signing of the Treaty of Aix‑la‑Chapelle, which ended the War of the Austrian Succession. The accord restored many territorial possessions to their prewar owners and left significant issues unresolved: the great powers exchanged colonies and prisoners, while continental settlements—most notably Prussia's retention of Silesia—reconfigured the balance of power. The treaty brought a temporary peace but also preserved tensions that later contributed to the Seven Years' War.
Science, law and ideas
1748 was important for intellectual history. Charles‑Louis de Secondat, baron de Montesquieu, published a major work on comparative government that argued for principles such as the separation of powers; its ideas became central to later constitutional thought. In mathematics, Leonhard Euler released an influential treatise that systematically developed analytic methods and helped shape modern mathematical analysis. These publications exemplify the period's combination of theoretical rigor and practical concern with institutions.
Culture and society
Artistically and socially, the mid‑18th century continued to favor Rococo taste in parts of Europe and growing public engagement with literature, opera and periodical debate. Commercial expansion and colonial competition drove economic and social change in Atlantic societies, and salons and learned societies carried Enlightenment debates across national borders. Scientific observation, travel reports and legal reform all entered broader public conversation.
Notable facts and people
- Treaty of Aix‑la‑Chapelle ended the War of the Austrian Succession and reshaped European diplomacy.
- Montesquieu published a key work on laws and constitutions that influenced later constitutional theory.

- Jeremy Bentham, later an important advocate of utilitarianism and legal reform, was born in this year.
As a calendar note, 1748 is conventionally treated as a leap year in the Gregorian cycle. The events and publications of 1748 are best seen as part of a gradual 18th‑century transformation: armed diplomacy and dynastic settlement coexisted with accelerating intellectual exchange, laying groundwork for the political and scientific changes that followed later in the century.
