Prior to World War II, 35mm film was marketed in 'loads'
for fitment to a proprietary cassette made by the camera
manufacturer. The purchaser would unwrap the load in the
dark, load the cassette, and then shoot the film in his
camera. This was long before the era of 100-foot bulk
rolls and Watson loaders.
Around 1935, Kodak pioneered the universal cassette in
which miniature-format (35mm) film has been marketed ever
since, even unto our own day.

One difference was in the way the leader was trimmed.
Leica cameras loaded from the bottom so the film had to be
slipped down into the gate. The leader had a tongue of film
with the long side facing the bottom of the camera. Contax
cameras had a removable back and the leader was cut as a
tongue of film centered symmetrically in order to fit the
slot on the take up spool. For a time 35mm film was sold in
cassettes to fit either pattern, other 35mm cameras being
made to take one or the other. I am not sure what
differences there were in the cassettes themselves. Both
Leica and Zeiss sold trimmers to cut bulk film to the right
shape.
The reloadable cassettes sold by the two companies are
not compatible because the light tight shutters are actuated
differently. Nikon uses Contax style cassettes, Canon I
think uses Leica style.
