**Ermengol** or **Armengol IV** (1056–1092), called **el de Gerb** or **Gerp**, was the [count of Urgell](/source/Count_of_Urgell) from 1066 to his death. He was the son of [Ermengol III](/source/Ermengol_III) and Adelaide.[a][b]

Ermengol inherited Urgell when he was only ten years old and ruled under the tutelage of the countess dowager, Sancha, third wife of his father, until he was twelve. During this brief minority, the nobility took the opportunity to plunder and occupy the comital demesne. It was not until 1075 that Ermengol had genuine control of his county and his nobles.

Ermengol was an active count. During his reign, Urgell profited economically, collecting tribute from [Lleida](/source/Lleida) and [Fraga](/source/Fraga). In 1076, having brought the nobles to submission, he began a [Reconquista](/source/Reconquista) of his own, taking the basin of the river [Sió](/source/Si%C3%B3) with the villages of [Agramunt](/source/Agramunt) and [Almenar](/source/Almenar) that year and [Linyola](/source/Linyola) and [Belcaire](/source/Belcaire) in 1091. He conquered [Calassanç](/source/Calassan%C3%A7) and built a castle at [Gerb](/source/Gerb,_Catalonia), Spain, where he later died, in an effort to pave the way to the recapture of [Balaguer](/source/Balaguer), which occurred during the reign of his son, [Ermengol V](/source/Ermengol_V_of_Urgell), in 1102.

Ermengol IV was a firm supporter of the contemporary [Gregorian reform](/source/Gregorian_reform) of the Church, which he introduced to Urgell. In 1077, Ermengol married Lucy, daughter of [Artau I, Count of Pallars Sobirà](/source/Artau_I,_Count_of_Pallars_Sobir%C3%A0),[1] and granddaughter of [Bernard I of La Marche](/source/Bernard_I_of_La_Marche). With her, he had his son and heir, the aforementioned Ermengol V.

In 1079, he remarried to [Adelaide of Forcalquier](/source/Adelaide_of_Forcalquier), daughter of [William Bertrand of Provence](/source/William_Bertrand_of_Provence). They had a son, [William](/source/William_III_of_Forcalquier),[2] who inherited [Forcalquier](/source/Forcalquier), and a daughter who died young. Ermengol IV died in 1092.

## Notes

1. In a charter dated 1066 – 1076, he appears as *Ermengaudum, Urgellensem comitem, filium Adalaidis comitisse* (Ermengol, count of Urgell, son of Countess Adelaide),[3] and, in another charter, dated 1069 – 1071, he identifies himself as *Ego, Ermengaudus comes Urgelli, filius qui sum comitisse Adalaidis* (I, Ermengol count of Urgell, son of Countess Adelaide). In this charter, he swears fealty to his brother-in-law [William I, Count of Cerdanya](/source/William_I,_Count_of_Cerdanya) and promises that if he died without issue, the County of Urgell would be inherited by his sister Isabella.[4]

1. Adelaide's family is not known with certainty, though some scholars have considered her the daughter of Guillem I, Count of Besalú.[1]
