How did Roman conquest and Christian missionaries spread the Latin alphabet?

The spread of the Latin alphabet was significantly influenced by Roman conquests and later by Christian missionaries. Roman legionaries and imperial officers carried the Latin language and script throughout the vast Roman Empire, particularly in regions that were not already Hellenized. This expansion established the Latin alphabet across much of Europe and North Africa.123

In later centuries, Christian missionaries played a crucial role in further disseminating the Latin alphabet. As Christianity spread, Latin, the language of the Roman Catholic Church, was carried to new lands. This religious expansion extended the reach of the Latin script beyond the former Roman territories, leading to its adoption by diverse linguistic groups across Europe and eventually worldwide. The development of distinct scripts like Carolingian minuscule, influenced by scholars like Alcuin under Charlemagne, also standardized and promoted the use of the Latin alphabet for book production.4135
