Here is a short Jain timeline from Ṛṣabhanātha to Mahāvīra:

• Ṛṣabhanātha (Ādinātha) — First Tīrthaṅkara; begins the Jain tradition and organizes human society.
• Ajitanātha to Pārśvanātha — The line of 22 Tīrthaṅkaras follows, each reviving and teaching the path of liberation.
• Pārśvanātha — 23rd Tīrthaṅkara; teaches the fourfold vows and is traditionally placed before Mahāvīra.
• Mahāvīra — 24th Tīrthaṅkara; gives the final full form of Jain teachings, including the five great vows.

In short: Ṛṣabhanātha → 22 Tīrthaṅkaras → Pārśvanātha → Mahāvīra

If you want, I can also give this as a one-line timeline with traditional dates.
