For the first few years of Henry II's reign the coins of King Stephen continued to be produced, but in 1158, a new 'cross and crosslet' coinage was introduced in England. While this coinage was acceptable in terms of weight and silver quality, it is notorious for its ugly appearance, bad craftsmanship and careless execution. It is a fact that this coinage is among the worst struck of any issue of English regal coinage. The cross and crosslet type coinage of King Henry II is more often called 'Tealby' because of the enormous hoard of these coins which was found in late 1807 at Bayons Manor farm near Tealby in Lincolnshire. This hoard, which originally amounted to over 5,700 pieces, was first reported in the Stamford Mercury of the 6th November 1807, but unfortunately the majority of the coins, more than 5,000 of them, were sent to be melted down at the Tower of London and only some 600 pieces were saved for national and important private collections.

Henry II became King of England in 1154 and reigned until his death in 1189. He was the first king of the House of Plantagenet. Henry became Count of Anjou and Maine upon the death of his father, Count Geoffrey V, in 1151, his marriage in 1152 to Eleanor of Aquitaine, whose marriage to Louis VII had recently been annulled, made him Duke of Aquitaine. He became Count of Nantes by treaty in 1185.
By the age of 14, Henry became actively involved in the efforts of his mother Matilda, daughter of Henry I of England, to claim the English throne, then occupied by Stephen of Blois. Stephen agreed to a peace treaty after Henry's military expedition to England in 1153, and Henry inherited the kingdom on Stephen's death a year later. Henry was an energetic and sometimes ruthless ruler, driven by a desire to restore the lands and privileges of his grandfather Henry I. During the early years of his reign Henry re-established hegemony over Wales and gained full control over his lands in Anjou, Maine and Touraine. Henry's desire to reform the relationship with the Church led to conflict with his former friend Thomas Becket, the Archbishop of Canterbury. This culminated in the murder of Becket by the high altar in his own church in 1170. This horrified Christians and, although Beckett was apparently disliked by the monks in life, in death he became a martyr, was canonised, and a religious cult grew up around his sainthood.
Henry II soon came into conflict with Louis VII, and the two rulers fought what has been termed a "cold war" over several decades. Henry expanded his empire at Louis's expense, taking Brittany and pushing east into central France and south into Toulouse, but despite numerous conferences and treaties, no lasting peace agreement was reached.
Henry and Eleanor had eight children—three daughters and five sons. As the sons grew up, tensions over the future inheritance of the kingdom began to emerge, encouraged by Louis and his son King Philip II. In 1173 Henry's heir apparent, "Young Henry", rebelled in protest; he was joined by his brothers Richard (later king) and Geoffrey and by their mother, Eleanor. France, Scotland, Brittany, Flanders, and Boulogne all allied themselves with the rebels. This “Great Revolt” was only defeated by Henry's vigorous military action and talented local commanders. Young Henry and Geoffrey revolted again in 1183, resulting in Young Henry's death. Henry II's invasion of Ireland provided lands for his youngest son John, but Henry struggled to find ways to satisfy all his sons' desires for land and immediate power. By 1189, Young Henry and Geoffrey were dead, and Philip successfully played on Richard's fears that Henry II would make John king, which led to a final rebellion. Henry II was decisively defeated by Philip and Richard and, suffering from a bleeding ulcer, he retreated to Chinon Castle in Anjou. Henry died soon afterwards and was succeeded by his son Richard I (the lionheart).
Many of the changes Henry II introduced during his long reign had long-term consequences, his legal changes are generally considered to have laid the basis for the English Common Law, while his intervention in Brittany, Wales, and Scotland shaped the development of their societies and governmental systems.
