I play the acoustic guitar - there are 3 main times of this guitar -  the classical guitar, the steel-string acoustic guitar, and the archtop guitar.
I thought there was just typically one type of guitar so that's interesting
It is also interesting that today's guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar
Can you perhaps explain to me what a gittern is?

It is usually depicted played with a quill plectrum, as we can see clearly beginning in manuscript illuminations from the thirteenth century.  
It was also called the guiterna in Spain, guiterne or guiterre in France, the chitarra in Italy and quintern in Germany. A popular instrument with court musicians, minstrels, and amateurs
type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument.
There are three main types of modern acoustic guitar: the classical guitar (Spanish guitar/nylon-string guitar), the steel-string acoustic
