==Between queenships==
Though she had left her role as queen of León, she retained authority over and taxing rights in many of the lands she had received there, including [[Salamanca]] and [[Castroverde]],{{sfn|Shadis|2010|pp=78–80}} which she gave to her son Ferdinand in 1206.{{sfn|Shadis|2010|pp=80,83–84}}  Some of the nobles who had served her as queen followed her back to the court in Castille.{{sfn|Shadis|2010|p=80}}  The peace which had prevailed since her marriage was lost, and there was war again between León and Castille, in part over her control of these lands.{{sfn|Shadis|2010|pp=83–84}}  In 1205, 1207, and 1209, treaties were made again between the two countries, each expanding her control.{{sfn|Shadis|2010|pp=78–84}}  In the treaties of 1207 and 1209, Berengaria and her son were given again significant properties along the border, including many key castles, including [[Villalpando]].{{sfn|Túy|2003|loc=4.84|p=324}}  The treaty in 1207 is the first existing public document in the [[Castilian Spanish|Castilian dialect]].{{sfn|Wright|2000}}

In 1214, on the death of her father, Alfonso VIII, the Castilian crown passed to his only surviving son, Berengaria's 10-year-old brother, Henry I.{{sfn|de la Cruz|2006|p=112}} Their mother Eleanor assumed the regency, but died 24 days after her husband.{{sfn|de la Cruz|2006|p=112}} Berengaria, now heir presumptive again, replaced her as regent.{{sfn|de la Cruz|2006|p=112}} At this point internal strife began, instigated by the nobility, primarily the [[House of Lara]].{{sfn|Shadis|2010|pp=86–91}} They forced Berengaria to cede regency and guardianship of her brother to Count [[Álvaro Núñez de Lara (died 1218)|Álvaro Núñez de Lara]].{{sfn|Shadis|2010|pp=86–91}}

In 1216, an extraordinary parliamentary session was held in Valladolid, attended by such Castilian magnates as [[Lope Díaz II de Haro]], [[Gonzalo Rodríguez Girón]], Álvaro Díaz de Cameros, [[Alfonso Téllez de Meneses "el Viejo"|Alfonso Téllez de Meneses]] and others, who agreed, with the support of Berengaria, to make common cause against Álvaro Núñez de Lara.{{sfn|Shadis|2010|pp=93–95}} At the end of May the situation in Castile had grown perilous for Berengaria, so she decided to take refuge in the castle of [[Autillo de Campos]], which was held by Gonzalo Rodríguez Girón (one of her allies) and sent her son Ferdinand to the court of his father.{{sfn|Shadis|2010|pp=93–95}} On 15 August 1216, an assembly of all the magnates of Castile was held to attempt to reach an accord that would prevent civil war, but disagreements led the families of Girón, Téllez de Meneses, and Haro to break definitively with Álvaro de Lara.{{sfn|Shadis|2010|pp=93–95}}
