Essex are back in Division One of the Specsavers County Championship after six years out of the top tier.
Their promotion was confirmed when they passed the 250 mark in their first innings against Glamorgan at Chelmsford, after Sussex had failed to take maximum batting points from their clash with Worcestershire.
That meant Essex only needed five points to secure a return to the top flight for the first time since 2010, with captain Ryan ten Doeschate and former skipper James Foster taking them over the line.
It had been a thoroughly professional performance by Essex throughout the season, leading the Divison for most of the summer following a sterling start.
They went eight games unbeaten, beginning with a comprehensive victory over Gloucestershire in which England captain Alastair Cook made 105 and international wannabe Tom Westley hit 121.
And the County never looked back, picking up six wins.
