Mangkunagara VIII faced extreme difficulty in maintaining the sovereignty of his state. As a result, the state of Surakarta (including Mangkunagaran) were incorporated into the province of Central Java in 1950. Mangkunagara VIII died in 1987 and was succeeded by his third child and second son as Mangkunegara IX.[1][2]
