## Body
### Early Life and Background  
Sebastian Cabot was born between 1476 and 1484 in the Republic of Venice, a maritime power renowned for its navigational and cartographic expertise. His birth name, Sebastiano Caboto, reflects his Venetian heritage. While details of his early life are scarce, his upbringing in a city-state dominated by trade and exploration likely influenced his career.  

### Career  
**Service to England (1497)**  
In 1497, Cabot commanded an expedition financed by England’s Henry VII, aiming to find a northwest passage to Asia. He sailed westward, possibly reaching Newfoundland or Labrador, though the exact landing site remains debated. This voyage reinforced England’s early claims to North American territories.  

**Service to Spain (1508–1557)**  
By 1508, Cabot had entered Spanish service, leading an expedition to South America in 1508–1509. He explored the Rio de la Plata, believing it might connect to the Pacific Ocean. Though the journey did not fulfill its economic goals, his charts of the region became foundational for later Spanish colonization.  

**Cartographic Legacy**  
Cabot’s 1544 world map synthesized his navigational experience, depicting the Americas with unprecedented accuracy for the time. It highlighted the Rio de la Plata and North American coastlines, serving as a reference for explorers and traders.  

### Exploration and Mapping  
Cabot’s voyages exemplified the Venetian tradition of combining trade, diplomacy, and scientific inquiry. His focus on charting navigable routes—rather than mere conquest—reflected the Republic of Venice’s emphasis on maritime commerce. The Rio de la Plata expedition, for instance, sought to open new trade pathways, mirroring Venice’s historical dominance in Mediterranean trade networks.  

### Later Life and Death  
Cabot died in 1557, likely in Spain, while planning another voyage. His death marked the end of an era for Venetian influence in Atlantic exploration, as rising powers like Spain and England increasingly dominated overseas ventures.  

### Legacy  
Cabot’s dual role as a Venetian operating in the service of rival crowns underscores his adaptability and the fluidity of allegiance among Renaissance explorers. His work not only advanced Spain’s and England’s colonial ambitions but also disseminated Venetian cartographic techniques across Europe. The accuracy of his maps and his pragmatic approach to exploration left a lasting imprint on the Age of Discovery, ensuring his recognition as a pivotal figure in the history of maritime navigation.
