Hadean
The Hadean () is a geologic eon of the Earth pre-dating the Archean. It began with the formation of the Earth about 4.6 billion years ago and ended, as defined by the ICS, 4 billion years ago. , the ICS describes its status as ""informal"". Geologist Preston Cloud coined the term in 1972, originally to label the period before the earliest-known rocks on Earth. W. Brian Harland later coined an almost synonymous term, the "Priscoan period", from "priscus", the Latin word for "ancient". Other, older texts simply refer to the eon as the Pre-Archean.
Hasmonean dynasty
The dynasty had survived for 103 years before yielding to the Herodian dynasty in 37 BCE. The installation of Herod the Great (an Idumean) as king in 37 BCE made Judea a Roman client state and marked the end of the Hasmonean dynasty. Even then, Herod tried to bolster the legitimacy of his reign by marrying a Hasmonean princess, Mariamne, and planning to drown the last male Hasmonean heir at his Jericho palace. In 6 CE, Rome joined Judea proper, Samaria and Idumea (biblical Edom) into the Roman province of Iudaea. In 44 CE, Rome installed the rule of a procurator side by side with the rule of the Herodian kings (specifically Agrippa I 41–44 and Agrippa II 50–100).
