The genealogy of the 421 and 414 follows back to the 411, the 421 starting life as a pressurized advancement of the 411.

The model 421 took to the skies without precedent for October 1965 (three years after the 411). In correlation to the 411 on which it was based, the 421 presented a lodge pressurization framework, all the more capable adapted and turbocharged GTSIO-520-D motors and a higher max takeoff weight. Conveyances of creation 421s started in May 1967, Cessna at the time asserting it as the least expensive pressurized twin available.

First and foremost upgrades to the 421 were offered with the 421a of 1969, however the 421b Golden Eagle of 1970 emphasized various critical enhancements including stretched nose and wing compass, while the motors held their energy to higher elevations than some time recently. The last statement of the 421 was the 421c accessible from late 1975, with a reinforced wet wing and no tip tanks, higher vertical tail, more productive props and new trailing connection undercarriage.

The 414 was produced as a less influential, lighter, easier and lower cost 421. First and foremost flown in 1968, it entered generation in 1969. It emphasizes the wings and fuselage of the 401 and 402 (themselves lighter advancements of the 411), or more guide drive, as opposed to equipped motors. The enhanced 414a Chancellor showed up in 1978, presenting the fortified wet wing without tip tanks. It stayed in generation until 1985.
