1558 (year)

Major events

• Loss of Calais: In January 1558 the French captured Calais, the last English possession on the mainland of France, ending a centuries-long English foothold across the Channel.
• Change of monarch in England: In November 1558 Queen Mary I of England died and was succeeded by her half-sister Elizabeth, beginning the Elizabethan era and a return toward Protestant policy in the years that followed.
• Livonian War begins: In 1558 Tsar Ivan IV of Russia launched an invasion of Livonia, initiating the prolonged conflict known as the Livonian War that drew in neighboring powers.

These events occurred against the backdrop of the Renaissance, continuing religious conflicts following the Reformation, and evolving dynastic politics across Europe. The capture of Calais removed a symbolic and strategic English foothold; Elizabeth's accession quickly reshaped English domestic and foreign policy; and the fighting in the Baltic altered the balance among northern states.

Context and consequences

The political shifts of 1558 had immediate and medium-term effects. England's loss of Calais was widely felt as an ignominious end to a long chapter of cross‑Channel entanglement. Elizabeth I's rise established a long and influential reign that steered England toward maritime expansion and religious settlement. The Livonian War set the stage for decades of conflict over access to the Baltic and influenced the rise of regional powers in northern and eastern Europe.

Number and notation

Viewed as an integer, 1558 is even and composite; its prime factorization is 2 × 19 × 41. In Roman numerals it is written MDLVIII. The year-number sits squarely in the middle of the 16th century and is often referenced in chronological summaries of the period because of the political turning points it contains.

Notable personal milestones in 1558 include high-profile deaths and successions that shaped national trajectories; the accession of Elizabeth I is the best-known example. While this year does not stand alone, it is often cited by historians for linking the end of one phase of Tudor policy to the start of another and for initiating conflicts that would reverberate across Europe.
