Despite the annoyance of being in a subordinate position with Aragon, plan for independence from the very beginning. Anyone who rivals Aragon will instantly support the player's independence after improving relations with them. The player should be wary of Aragon making an alliance with the Papal States or other local powers on the peninsula, as this can complicate the war.

Naples can ask for support for independence of other nations. The best case scenario is when both Austria and Castile rival Aragon. This will let Naples get a support independence treaty with both of these nations. Before starting off, the player could max out the force limits and ask for support for independence from Austria and Castile. Then they could improve relations with Austria. When the truce is over, the player could declare war. Austria and Castile will be immediately called in. Continuing to improve relations with Austria until Naples can join the HRE is a good idea. At Naples' current size (with the Sicilian cores) they can just barely join the HRE, although this is not a necessity. If possible, ask Aragon for cores back, as well as independence. Sicily is very important in expanding into Africa if one so chooses.
After independence, it's up to the player to choose where to expand. There are many options available due to Naples' size. If Naples joins the HRE, attempting to become Emperor is an option, although this has to be done before the shadow kingdom event to prevent the triggered modifier for staying in the empire. Another option is colonizing the new world. One could easily snap up a ton of North America as Naples but funneling trade to Genoa requires power in the Bordeaux node. A better expansion option may be Africa, trade from West Africa may be pulled across the Sahara to Tunis and on to Genoa. This path of expansion requires Exploration ideas, which can be dropped after bridging the provinces south of Fezzan. Another path could be to expand into Italy and reap the riches of others, in this case claiming across sea zones to attack Siena, Genoa or Ferrara could be a good idea if The Papal State has good allies. A French alliance is quite common with Naples so this could assist in Neapolitan endeavors. Releasing nations to diplomatically vassalize to prevent high aggressive expansion (such as Modena and Parma, or even Avignon if the player is fast enough) might be a good idea. Naples may consider expanding eastward through Ragusa or Serbia into the Balkans and Hungary, outside of the HRE and lead the crusade against the Ottomans, it is recommended to only start to do this after forming Italy, as it will be difficult beforehand. Blocking off the Ottomans from their Balkan territories from the straits is an effective way to siege out quite a bit of their richer provinces, including their capital. Taking lands and releasing Byzantium is quite an effective way of gaining more cores. The Indian path is also easy to achieve provided Naples has swept through North Africa to the Mamluks faster than the Ottomans can get to them or Naples has already taking Suez from the Ottomans.
