Crete and Cyrenaica in the context of "Roman Libya"

Cyrenaica (/ˌsaɪrəˈneɪ.ɪkəˌˌsɪr-/ SY-rə-NAY-ik-ə-,-SIRR-ə) or Kyrenaika (Arabic: برقة, romanized: Barqah, Koine Greek: Κυρηναϊκή [ἐπαρχία], romanized: Kūrēnaïkḗ [eparkhíā], after the city of Cyrene), is the eastern region of Libya. Cyrenaica includes all of the eastern part of Libya between the 16th and 25th meridians east, including the Kufra District. The coastal region, also known as Pentapolis ("Five Cities") in antiquity, was part of the Roman province of Crete and Cyrenaica, later divided into Libya Pentapolis and Libya Sicca. During the Islamic period, the area came to be known as Barqa, after the city of Barca.

Cyrenaica became an Italian colony in 1911. After the 1934 formation of Italian Libya, the Cyrenaica province was designated as one of the three primary provinces of the country. During World War II, it fell under British military and civil administration from 1943 until 1951, and finally in the Kingdom of Libya from 1951 until 1963. The region that used to be Cyrenaica officially until 1963 has formed several shabiyat, the administrative divisions of Libya, since 1995. The 2011 Libyan Civil War started in Cyrenaica, which came largely under the control of the National Transitional Council (headquartered in Benghazi) for most of the war. In 2012, a body known as the Cyrenaica Transitional Council unilaterally declared Cyrenaica to be an autonomous region of Libya.

During the era of the Roman Empire, most of modern-day Egypt except for the Sinai was ruled as the imperial province of Aegyptus, from the time it was conquered by Roman forces in 27 BC, to AD 642. The province was bordered by Crete and Cyrenaica to the west and Judaea, later Arabia Petraea, to the East.

Egypt came to serve as a major producer of grain for the empire and had a highly developed urban economy. It was by far the wealthiest Roman province outside of Italy. The population of Roman Egypt is unknown, although estimates vary from 4 to 8 million. Alexandria, its capital, was the largest port and second largest city of the Roman Empire.
