History of England
With Henry VII's accession to the throne in 1485, the Wars of the Roses came to an end, and Tudors would continue to rule England for 118 years. Traditionally, the Battle of Bosworth Field is considered to mark the end of the Middle Ages in England, although Henry did not introduce any new concept of monarchy, and for most of his reign his hold on power was tenuous. He claimed the throne by conquest and God's judgement in battle. Parliament quickly recognized him as king, but the Yorkists were far from defeated. Nonetheless, he married Edward IV's eldest daughter Elizabeth in January 1486, thereby uniting the houses of York and Lancaster.
Tudor batteries
In 1901, Henri Tudor decided to change the name of the firm to "Société anonyme des accumulateurs Tudor" (Anonymous society of the Tudor Accumulator) with operating sites in Lille and Florival. Later in 1908, the Rosport site was closed. As Tudor Spain became more profitable, the shareholding shifted and the majority shareholder became the Germany Company (AFA) and Tudor imported equipment from Germany.
When the first world war broke out in 1914, AFA removed from Tudor Spain's capital. Three directors resigned and the situation was critical. However, in 1916, Tudor Spain became the supplier of two starting batteries models manufactured in Spain. In others European countries during WWI, plants were completely plundered, like in Belgium and in Luxembourg. These events will not hinder the company to have, between the two world wars nearly 25,000 employees at the Florival plant. In 1920, Tudor Spain supplied the first battery for a submarine (Isaac Peral), with funding from The Akkumulator Fabrik AG.
